Preface: Nsight Systems is a tool for developers who need to understand the big picture of application execution on heterogeneous systems, especially in scenarios involving data transfer bottlenecks between the CPU and GPU or scaling across multiple nodes.
Background: In NVIDIA Nsight Systems, process_nsys_rep_cli[.]py is an internal Python script used primarily for post-processing and report generation from raw profiling data.
While users typically interact with the nsys command-line tool, this script is invoked behind the scenes during the following operations.
Why This Might Connect to Nsight Systems?
Nsight Systems allows exporting [.]nsys-rep files and then processing them with scripts like process_nsys_rep_cli[.]py.
If the CLI or scripts read commands or code from user-provided files without validation, it could lead to:
-Command injection (similar to os[.]system()).
-Code execution (similar to exec()).
The design flaw could be that Nsight Systems assumes [.]nsys-rep or related files are safe, but if an attacker crafts a malicious file and you run the processing script, it could execute harmful commands.
Vulnerability details: CVE-2025-33228 NVIDIA Nsight Systems contains a vulnerability in the gfx_hotspot recipe, where an attacker could cause an OS command injection by supplying a malicious string to the process_nsys_rep_cli[.]py script if the script is invoked manually. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure.

Preface: Many people develop a strong interest in science and space when they gaze at the stars at nightfall. The boundless potential of human thought and imagination holds limitless possibilities, and young people are eager to explore this realm. In fact, everyone possesses.
Background: Interstellar comet 3I/ATLAS aligns with the Sun-Earth axis on January 22, 2026, offering scientists what researchers describe as a once-in-decades opportunity to study pristine material from another star system.
At solar opposition, the anti-tail jet will be pointing at Earth, said Professor Avi Loeb.
Solar Radiation Storm Forecast for Jan 20-Jan 22 2026 Jan 20 Jan 21 Jan 22 S1 or greater 99% 95% 65% Rationale: An S2 (Moderate) solar radiation storm is in progress at the time of this summary. S1 (Minor) radiation levels are expected on 21-22 Jan.
My imagination: If 3I/ATLAS’s “anti-tail” point to earth. Coincidentally 22nd JAN 2026 earth magnet field defense strong solar wind from Sun. Assume the magnetic have chance intercept with 3I/ATLAS anti-tail. Because 3I/ATLAS’s “anti-tail” (a sunward extension of its coma) and unusual chemical composition are linked to the sublimation of volatile compounds, especially carbon dioxide (CO2cap C cap O sub 2𝐶𝑂2), methanol, hydrogen cyanide (HCN), and potentially organometallic molecules like nickel carbonyl, which vaporize to create jets and unusual dust pattern. It is strong. In this scenario. Does it have change in earth atmosphere?
If the anti-tail of 3I/ATLAS points towards Earth, and Earth’s magnetic field happens to resist the strong solar wind from the Sun on January 22, 2026, let’s assume the magnetic field encounters the anti-tail of 3I/ATLAS. Since the anti-tail of 3I/ATLAS (the portion of its coma extending towards the Sun) and its anomalous chemical composition are associated with the sublimation of volatile compounds, particularly carbon dioxide (CO₂), methanol, hydrogen cyanide (HCN), and potential organometallic molecules (such as nickel carbonyl), these substances would vaporize to form jets and unusual dust distribution. In this scenario, would Earth’s atmosphere change?
A magnetic field promotes the adsorption of CO2 and H2 onto the surface of magnetized catalysts. This facilitates the reaction between CO2 and hydrogen to produce methanol. If methanol located in space and approach of the outer layer of atmosphere? What is the impact?
If methanol located in space were to approach Earth’s outer atmosphere, its impact would be defined by rapid chemical breakdown and atmospheric heating rather than direct environmental contamination. Does it mean the earth temperature increased?
Yes, if methanol from space were to enter the atmosphere, it would contribute to a rise in Earth’s temperature, though primarily through indirect chemical pathways rather than the heat generated during its entry.
Despite these warming effects, Earth has natural “sinks” that limit methanol’s impact:
Short Lifetime: Methanol only stays in the atmosphere for about 5 to 12 days.
Oceanic Absorption: The ocean acts as a major “sink,” quickly absorbing and depositing methanol that reaches lower altitudes, which helps mitigate its long-term warming effect.
Therefore, we can safely observe this astronomical phenomenon.
Preface: Data engineers perform seamless preprocessing, a foundational stage where they gather messy, raw data from diverse sources, clean it (handling missing values, outliers, inconsistencies), integrate disparate datasets, and transform it into a unified, structured format, making it ready and reliable for data scientists to perform advanced feature engineering (creating new, meaningful features) and ultimately build better machine learning models. This ensures a high-quality, consistent input, preventing “garbage in, garbage out” for the modeling phase.
Background: Transformers4Rec is pre-installed in the merlin-pytorch container available from the NVIDIA GPU Cloud (NGC) catalog. This container is part of the NVIDIA Merlin ecosystem and is specifically designed to support sequential and session-based recommendation tasks using PyTorch.
The workflow can show you where we speculated design weakness of CVE-2025-33233.
NVTabular for preprocessing → PyTorch for training → Triton for serving—means PyTorch is a critical component. If its loading function is insecure, Merlin’s container is exposed regardless of NVIDIA’s own code. The workflow can display the location of suspected design flaw CVE-2025-33233.
If Transformers4Rec internally uses torch.load (which is common for loading PyTorch models) and relies on weights_only=True for safety, then CVE-2025-32434 could be the root cause or at least a contributing factor.
NVIDIA might have classified it as a separate CVE because the exploit path involves their product’s integration with PyTorch, making it a product-level exposure rather than just a dependency issue.
Vulnerability details: CVE-2025-33233 NVIDIA Merlin Transformers4Rec for all platforms contains a vulnerability where an attacker could cause a code injection issue. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, information disclosure, and data tampering.

Preface: Elon Musk has warned that the rapid advancement of artificial intelligence and electric vehicles (EVs) is creating an “enormous demand” for electrical equipment and power generation, predicting a potential, severe electricity shortage as early as 2025.
About 3I/ATLAS: The interstellar comet 3I/ATLAS’s core is confirmed to be rotating, with observations revealing wobbling jets and a distinctive, changing “cupcake” brightness pattern, indicating a rotation period around 16 hours, but scientists are still investigating the exact cause of these unique, rapid rotational dynamics. These observations suggest complex outgassing or structural properties unlike typical solar system comets, sparking significant scientific interest and online discussion.
If the materials in the 3I/ATLAS core can generate high temperatures when passively receiving solar radiation, then it might be the next generation of energy. If this dream comes true, it’s just another coincidence! Because aliens didn’t appear , but rather guided you onto the right path in the future.
For example: The Moon’s surface, particularly its top layer of soil (regolith), contains significantly more Helium-3 (He-3) than Earth, deposited by solar winds over billions of years, making it a valuable potential resource for future clean energy (fusion) and high-tech applications like quantum computing, despite current extraction challenges.
Philosophy: Both creator and destroyer!
Humanity has created an artificial intelligence world, and Homo sapiens on Earth tell us we are entering a new era. This is truly exciting news… But if the creator of artificial intelligence represents God, did he missed a balance this new technology?
Preface: This article is scheduled for release on January 21, 2026. It may contain some key topics that will be helpful to developers. Therefore it release today.
The “spyware” mentioned in April 2025 was the Apple Company policy, but the attacks reported in January 2026 are live threats using newer exploits (CVE-2025-43529 and CVE-2025-14174). If you have not updated to iOS 26.2 or newer, your device is at high risk from these “extremely sophisticated” attacks.
Background:
ANGLE on iOS: Chrome on iOS uses WebKit as its rendering engine (due to Apple’s App Store policy), and ANGLE is integrated for WebGL translation.
WebKit Zero-Day Exploits: If attackers exploit WebKit vulnerabilities (like CVE-2025-43529) and combine them with ANGLE flaws (CVE-2025-14174), they can potentially achieve remote code execution or device compromise.
Shared Components: Safari and Chrome on iOS both rely on WebKit, so any ANGLE-related bug in WebKit’s GPU pipeline could propagate to iOS.
Cyber security focus – CVE-2025-43529
When the JIT compiler requests executable memory via jit_heap and writes machine code, bmalloc/libpas allocates memory regions. If an object or memory block is freed prematurely and then accessed, that’s where UAF occurs. Complex DOM/JS operations or JIT optimizations often trigger these conditions.
The CVE-2025-43529 is tied to a use-after-free in WebKit’s internal memory management (bmalloc/libpas) during complex DOM/JS operations.
Cyber security focus – CVE-2025-14174
A security issue was found in ANGLE regarding gl.deleteTexture().
Asynchronous Release Bottlenecks: A known behavior is that calling gl.deleteTexture() does not immediately free memory if the GPU is still processing draw calls that reference that texture. Memory is only reclaimed after the GPU finished execution.
Shader Translation Memory Retention: A discovered bug in ANGLE’s PoolAllocator revealed that it often moves single-page allocations to a free list rather than returning them to the OS, causing memory used during shader translation to persist until the compiler instance is destroyed.
The following detailed information explains the relationship between ANGLE and different web browsers.
-Google Chrome Full Support (v1.0 & v2.0) Uses ANGLE
-Mozilla Firefox Full Support (v1.0 & v2.0) Uses ANGLE (on Windows) or own implementation
-Apple Safari Full Support (v1.0 & v2.0) Uses ANGLE (since v15+)
-Microsoft Edge Full Support (v1.0 & v2.0) Uses ANGLE (Chromium-based)
These vulnerabilities were actively exploited in the wild, often in spyware campaigns targeting high-profile individuals.
Even if you’re not a high-risk target, updating was critical because these flaws allow remote code execution via a crafted webpage.
For more details on these matters, please see the link.
Preface: ETSI TS 07.10 defines the multiplexer protocol for GSM networks, and DLCI 0 (Data Link Connection Identifier 0) specifically refers to the control channel used to manage multiple virtual serial sessions (like data, fax, voice) over a single physical serial link or its wireless emulation (like Bluetooth’s RFCOMM) to a device, essentially acting as the “local serial line” manager for those simultaneous connections on a smartphone or modem.
Background: In 2026, firmware-level flooding attacks over RFCOMM (Radio Frequency Communication) channels primarily exploit the device’s inability to handle excessive signaling and control traffic, leading to resource exhaustion or firmware crashes. These attacks typically occur without the need for prior pairing or authentication.
Assumed earbuds firmware is the vulnerable component because it acts as the Responder on DLCI 0 and processes ETSI TS 07.10 control commands (like TEST) without proper limits.
The attacker (or smartphone) sends the flooding traffic, but it’s lightweight for the sender—just repeated TEST frames.
The earbuds do all the heavy lifting: parsing, allocating buffers, and responding. This leads to resource exhaustion on the earbuds, not on the smartphone.
The earbuds will run out of resources (CPU/memory) due to excessive TEST frames, not the smartphone.
Vulnerability details: This vulnerability is caused by the firmware’s susceptibility to flooding attacks over RFCOMM channels. When an attacker floods the standard control channel (DLCI 0) with a high volume of legitimate TEST commands, the device’s processing queue is overwhelmed, leading to resource exhaustion and a firmware crash that forcibly terminates paired user connections. Other active data channels across the device’s RFCOMM implementation are also vulnerable to flooding via MSC (Modem Status Command) signaling frames, including both the standard HFP (Hands-Free Profile) channel and an undocumented Airoha auxiliary service channel.
Preface: CVE-2025-29943 allows disabling AES-NI at runtime, forcing mbedTLS to fall back to a vulnerable software AES implementation. In SGX enclaves, this enables cache-timing attacks to recover AES keys.
Attack Prerequisites:
Privileged access inside the VM (root or equivalent).
Ability to manipulate CPU feature bits or configuration.
Background: An SGX enclave (Software Guard eXtensions) is
a secure, isolated area within a computer’s processor and memory, creating a Trusted Execution Environment (TEE) for running sensitive code and data, protected even from the OS, hypervisor, or BIOS.
A specific undocumented bit can disable AES-NI at runtime, forcing the AES portion of mbedTLS to “fall back” to a version vulnerable to caching attacks. Utilizing this “fallback” in an SGX enclave, it can fully restored the enclave to use the AES key. Therefore, the vulnerability allows an attacker to extract (recover) the existing secret key.
Ref: The stack pointer (SP) inside an SEV-SNP guest is a critical CPU register, protected by SEV-SNP’s memory encryption and integrity features, but recent attacks like StackWarp and CacheWarp exploit microarchitectural side channels (often involving hyperthreading or cache timing) to infer or manipulate the SP and other sensitive state, potentially bypassing SEV-SNP’s security by observing how memory/cache changes during execution, allowing attackers to hijack control or leak data.
Vulnerability details: CVE-2025-29943: Improper access control within AMD CPUs may allow an admin-privileged attacker to modify the configuration of the CPU pipeline, potentially resulting in the corruption of the stack pointer inside an SEV-SNP guest.
Remark:
-Privileged accounts are not immune to compromise (e.g., insider threats, privilege escalation).
-Cloud or virtualized environments often assume strong isolation, but if an attacker gains root/admin inside the VM, they can exploit this vulnerability.
-The vulnerability affects cryptographic integrity and confidentiality, which is critical for SGX and secure workloads.
Reminder: It’s not a remote exploit, but local privileged exploits are still considered medium-risk (4.6) because:
They can lead to full compromise of sensitive data.
They break the security guarantees of SGX and SEV environments.

Preface: If 3I/ATLAS is a detector, it would observe Field-Aligned Currents (FACs)—massive electrical currents flowing along magnetic field lines toward the North and South poles.
Prediction and Imagination:
The only “alignment” on January 22, 2026 is the rare, nearly perfect straight line configuration of the Sun, Earth, and 3I/ATLAS, with Earth in the middle. The Moon’s position in its orbit around Earth does not coincide with this event.
The moon is crucial to Earth. It controls the tides of the oceans. The properties of the tides act like a controller, regulating the Earth’s rotation speed. But nobody cares where the moon will be on January 22, 2026. 3I/ATLAS has garnered worldwide attention. However, suspected UFO incidents on Earth are not limited to this. Let’s review a Chinese story, it is documented in the Tang Dynasty text titled Youyang Zazu (酉阳杂俎), written by Duan Chengshi (段成式) around 860 AD. The story, titled “The Moon Repairer,” describes an encounter between two travellers and a mysterious man in a white robe.
The story, titled “The Moon Repairer,” describes an encounter between two travelers and a mysterious man in a white robe.
Key Details from the Tang Dynasty Story
The Encounter: Two men, Zheng and Li, were lost on Mount Song at night when they found a man in thick, “snow-white” robes sleeping in a pavilion.
The Repairman: When asked where he came from, the man pointed to the moon and claimed to be one of 82,000 workers responsible for repairing it.
Advanced Descriptions: Long before modern telescopes, the “man from the moon” explained two scientific facts to the travellers:
Surface Texture: He stated the moon is not a smooth mirror but is rugged and uneven (mountainous).
Light Source: He explained that the moon does not produce its own light but only reflects the light of the sun.
Historical Significance: While ancient Chinese people primarily believed the Earth was flat and the sky was a dome (the “Tian Yuan Di Fang” or “Round Heaven, Square Earth” theory), this story is often cited by modern enthusiasts as a “pre-modern” science fiction or even an early account of an “alien encounter.
In conclusion, the discovery of new objects or advanced civilizations is not limited to the discoveries of modern scientists. They may have already been involved in our historical process.
Unvalidated library loading (similar to LD_PRELOAD abuse).
Potential exploitation via malicious shared objects ([.]so files) placed in search paths.
Attackers could leverage writable directories or environment variables (like LD_LIBRARY_PATH) to inject malicious code when Nsight starts profiling.
Background:
Nsight Compute – As an interactive kernel profiler for CUDA applications, Nsight Compute provides detailed performance metrics and API debugging via a user interface and command line tool. Nsight Compute also provides customizable and data-driven user interface and metric collection that can be extended with analysis scripts for post-processing results.
Nsight Graphics – This is a standalone development tool for debugging, profiling and analysing graphics applications. Nsight Graphics allows optimization of performance of Direct3D 11, Direct3D 12, DirectX Raytracing 1.1, OpenGL, Vulkan, and KHR Vulkan Ray Tracing Extension based applications.
Injection allows tools like NVIDIA Nsight Graphics to sit between your application and the graphics driver to intercept, record, and manipulate the stream of commands.
Don’t underestimate the value of independent developer workstations. Sometimes, these workstations may store product prototypes and notes. If this information is intellectual property, and the workstation is located within the development team’s network segment, a cyberattack could not only lead to information leaks but also cause financial losses!
Vulnerability details: CVE-2025-33206 – NVIDIA NSIGHT Graphics for Linux contains a vulnerability where an attacker could cause command injection. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, and denial of service.
Remark: If Nsight runs with elevated permissions (common for GPU profiling), exploitation can lead to:
Arbitrary code execution.
Escalation of privileges.
Data tampering or denial of service.

Preface: The vulnerability described in AMD-SB-7038 is based on a general microarchitectural behavior: memory reordering and out-of-order execution. These techniques are used by all major CPU vendors (Intel, ARM, etc.) to improve performance.
Background: The bulletin describes a research paper titled “MEMORY DISORDER: Memory Re-orderings as a Timerless Side-channel.”
Key points from AMD’s disclosure:
Nature of the issue: Researchers demonstrated that memory re-orderings in CPUs and GPUs can be exploited as a timerless side-channel attack. This means attackers can infer activity in other processes by observing subtle memory ordering patterns—without using timing measurements.
Impact:
Potential for covert channels (secret communication between processes).
Possible application fingerprinting (detecting what app is running).
No direct data corruption or privilege escalation, but information leakage risk.
Scope:
Applies to mainstream processors, including AMD CPUs and GPUs.
It’s informational, not an emergency patch scenario. AMD classifies it as low severity because exploitation requires local access and advanced techniques.
