CVE-2026-80725: Allows unauthorized protocols to bypass the maximum 64KB legacy packet size limit. (1st Sep 2026)
Preface: Modern high-performance network stacks, particularly those in Linux-based CDN edge routing fabrics, utilize Generic Receive Offload (GRO) for GRE traffic. In fact, GRO is essential for handling GRE-encapsulated DDoS or DSR traffic at line-rate speeds (such as 10Gbps, 40Gbps, or 100Gbps) without completely exhausting the host’s CPU. Background: Without GRO, a Linux server handling…

CVE-2026-24262 and CVE-2026-24263 specifically address out-of-bounds writes in the DGX Spark system firmware. Design weakness fixed on 25th Aug 2025.
Preface: When running workloads like Apache Spark using CUDA acceleration on an NVIDIA DGX Spark (powered by the GB10 Grace Blackwell Superchip), the performance improvement over a top-grade Intel or AMD CPU desktop is massive—often ranging from 3x to over 20x faster, depending on the exact task. Background: The design goal of the Nvidia DGX…

Regarding CVE-2026-65083, CVE-2026-65092, and CVE-2026-65093 related to NVIDIA OpenShell Linux Sandbox and NVIDIA NEMOCLAW (28th Aug 2026)
Preface: If a sandbox platform evaluates an L7 policy (such as inspecting HTTP methods or URL paths), it must actively recognize the traffic as HTTP/REST. If an attacker wraps a REST payload inside an uninspected protocol, encrypts it via custom TLS tunnels, or forces a raw TCP connection, the L7 relay often becomes blind. Many…

My thoughts on NVIDIA Rowhammer security bulletin released on August 25, 2026.
Preface: The classic open-source code used to test Rowhammer (including verifying whether ECC can completely block it) primarily comes from Google’s Project Zero, CMU’s Safari Lab, and various chip security research teams. Background: The real culprit is density: The underlying vulnerability of Rowhammer is caused by physical electrical leakage between adjacent memory rows. As manufacturing…

CVE-2026-59568: Several vulnerabilities in the affected version of Zscaler Client Connector have been fixed.
(Publication date of this article: August 26, 2026) Preface: While a VPN tunnel safely encrypts data from your device to the endpoint, it acts like a wide-open pipe. If malware infects your laptop, it can travel through that encrypted tunnel straight to your company’s core data center. Zscaler inspects all traffic in real-time within its…

Point of view on the remediation of CVE-2026-74724 – Linux kernel ipvs module (25-08-2026)
Preface: Today, I want to walk you through a critical vulnerability rooted deep within the Linux kernel networking stack: CVE-2026-74724, and discuss how it impacts modern cloud-native environments. Background: As we know, when a Kubernetes cluster scales, the default iptables backend suffers from severe performance degradation due to its O(n) sequential rule matching. To handle…

CVE-2026-24183 and CVE-2026-24184: About NVIDIA Cumulus Linux (24th Aug 2026)
Preface: About 26 years ago, mainframe computers—especially the IBM S/390—installed FICON switches with optical fiber connections to interconnect with host nodes. As time went by, the design of supercomputers relied more heavily on Linux-based HPC (High-Performance Computing) clusters. Nvidia’s CUDA tools empowered traditional 64-bit instruction sets (which favor sequential processing) to extend into GPU multiprocessing…

CVE-2026-65349 is an out-of-bounds read vulnerability (CWE-125) in the XNU Kernel caused by inadequate input validation of data_length in IOKit interactions. (21st Aug 2026)
Preface: CVE-2026-65349 is a vulnerability located inside the XNU kernel. Although it is often triggered by attackers using WebKit as a springboard, its fundamental flaw lies in the lack of strict boundary checks when the kernel parses input parameters from user space (through calls like ioctl/IOKit), leading to out-of-bounds reads of kernel memory. Background: After…

The evolution sequence of vulnerabilities in the NVIDIA Triton inference server (CVE-2026-47629, CVE-2026-47627, CVE-2026-47628 and CVE-2026-47606). 20th Aug 2026
Preface: NVIDIA Dynamo-Triton and Triton inference server are functionally identical; NVIDIA Dynamo-Triton is simply the new name for the Triton inference server. NVIDIA has integrated Triton into its broader Dynamo platform and officially renamed it Dynamo-Triton. Thousands of enterprises and technology brands worldwide use NVIDIA Triton inference servers (now integrated into NVIDIA Dynamo-Triton) to run…

CVE-2026-25289: Stack-based buffer overflow/memory corruption flaw found by Qualcomm (19th Aug 2026)
Preface: Mercedes-Benz has integrated the Snapdragon Auto 5G Modem-RF platform directly into its newest vehicle architectures. Porsche relies on Qualcomm hardware through a long-term, group-wide technology agreement between its parent company, the Volkswagen Group, and Qualcomm. Ref: Qualcomm notified customers of a product design weakness (CVE-2026-25289) on May 4, 2026. The issue has been resolved.…
