CVE-2026-79839: A buffer overflow vulnerability in HPE NonStop ODBC/MX Server
This article was published on October 16, 2026. Preface: The HPE NonStop ODBC/MX connectivity architecture operates through the NonStop SQL/MX Connectivity Service (MXCS), which implements the Open Database Connectivity (ODBC 3.5 / 3.0) standard to interface client applications with the ANSI-compliant NonStop SQL/MX database. Background: The following instructions require the use of the accompanying infographics.…

When executing this on CPython 3[.]13 and earlier, it exposes your application directly to CVE-2026-82049.
This article was published on September 17, 2026. Preface: Artificial intelligence does indeed threaten human jobs. But itself contains not less design weakness because it extreme fast growth of development. The competition is major element embedded in human DNA fundemental. “Natural selection” (often paired as “Survival of the fittest”) is the core concept of the…

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…

AMD ID- AMD-SB 7062: About Efficient Symbolic Execution design weakness (18th Aug 2026)
The security bulletin was published by AMD on August 12, 2026. Preface: Linux was introduced to High-Performance Computing (HPC) in the late 1990s, fundamentally transforming how we build powerful machines. Before this shift, traditional supercomputers were dominated by proprietary systems from vendors like Cray, IBM, and Bull. These legacy systems relied on specialized vector processors…

Third-party opinions on CVE-2026-6727 (non-AMD), associated with AMD ID: AMD-SB-7064 (13th Aug 2026)
Preface: The AMD EPYC 9004 and 9005 series processors heavily demand—and absolutely dominate—the High-Performance Computing (HPC) and AI markets. Because CPUs and GPUs have fundamentally different processing architectures, there is no single “1-to-1” equivalence. Instead, the number of AMD EPYC 9005 (Zen 5 “Turin”) processors needed to equal one NVIDIA H100 GPU depends entirely on…

About AMD-SB 3032: Extracting VM Secrets through Power Side Channels on AMD SEV-ES and SEV-SNP (12th Aug 2026)
Preface: AMD EPYC processors include RAPL (Running Average Power Limit) functionality, which provides a standardized cross-vendor interface for enterprise data centers. Enterprise Linux ecosystems rely heavily on built-in diagnostic and orchestration frameworks. By exposing counters through the RAPL standard via the Linux PowerCap and perf subsystems, server administrators can monitoring AMD hardware. Background: AMD Secure…

Detailed description of the AMD-SB-7061 Safe RET interrupt vulnerability.
This article was published on 10th Aug 2026 Official release date: August 4, 2026 Preface: AMD Zen 4 architecture is widely used in high-performance computing (HPC). It powers 4th Generation AMD EPYC server processors (such as Genoa, Genoa-X with 3D V-Cache) and the AMD Instinct MI300A accelerated processing unit (APU), which combine Zen 4 CPU…

Overcoming virtualization bottlenecks (Hyper-V & PCIe) 11th Mar 2026
Preface: Microsoft Hyper-V is used less than Docker and Kubernetes (K8s) in modern application deployment primarily because Docker and K8s offer superior resource efficiency, portability, speed, and scalability, making them better suited for modern cloud-native architectures like microservices. Hyper-V, as a traditional hypervisor, provides robust isolation but operates at a different layer of the infrastructure…

AMD ID: AMD-SB-7055RDSEED Failure on AMD “Zen 5” Processors(27th-10-2025)
Preface: The main consequence of an RDSEED failure on AMD Zen 5 processors is instability, crashes, and potentially corrupted data, as this issue affects the processor’s ability to generate high-quality random numbers for cryptography and other sensitive tasks. This has led to the development of Linux kernel patches to temporarily disable RDSEED on affected Zen…
