Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, amd64-microcode

A side channel vulnerability in some AMD CPUs may allow an attacker to influence the prediction of the return address. This could result in speculative execution at an address controlled by the attacker, potentially leading to the disclosure of information...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

There is a vulnerability in the Linux Kernel within the KVM framework: nVMX, which allows for speculative execution attacks. L2 can execute Spectre v2 attacks on L1, as L1 believes it does not need retpolines or IBPB after executing L2, due to KVM L0 indicating support for eIBRS to L1. An attacke...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw in the boot CPU could be exploited by attacks targeting speculative execution behavior. This flaw is related to the power management options in the Linux kernel’s X86 CPU. It was discovered in the way users resume the CPU from suspend-to-RAM. A local user could utilize this flaw to...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

Intel’s microprocessor generations 6 to 8 are affected by a new Spectre variant that can bypass the retpoline mitigation mechanism in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to execute arbitrary speculative code under certain...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs: prevent out-of-bounds array speculation when closing a file descriptor Google-Bug-Id: 114199369...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Use arrayindexnospec with indices that come from the guest. min and destid are guest-controlled indices. Using arrayindexnospec after the bounds checks helps to mitigate speculative execution side-channels...

Astra Linux – Vulnerability in Linux, Linux 5.15

When SMT is enabled, certain AMD processors may speculateively execute instructions using a target from the sibling thread after a SMT mode switch, which may potentially lead to information disclosure...

Astra Linux – Vulnerability in Xen

Potential speculative code storage bypasses exist in all supported CPU products. Combined with software vulnerabilities related to speculative execution of overwritten instructions, this could lead to incorrect speculation and potentially cause data leakage...

SUSE CVE-2023-20569

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure...

Unity Linux 20.1060e / 20.1070e Security Update: binutils (UTSA-2026-017633)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017633 advisory. Load value injection in some IntelR Processors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a sid...

Janus: Compiler-Based Defense against Transient Execution Attacks Using ARM Hardware Primitives

We present Janus, a compiler-based security framework that mitigates transient execution attacks like Spectre and control-flow hijacking on ARM64 platforms. Janus integrates speculative execution and control flow dependencies with PA modifiers, using PA and BTI microarchitectural features to...

SUSE CVE-2026-31781

In the Linux kernel, the following vulnerability has been resolved: drm/ioc32: stop speculation on the drmcompatioctl path The drm compat ioctl path takes a user controlled pointer, and then dereferences it into a table of function pointers, the signature method of spectre problems. Fix this up b...

CVE-2026-31781

A flaw was found in the Linux kernel's Direct Rendering Manager DRM subsystem, specifically in the drm/ioc32 component. This vulnerability, related to speculative execution a technique used by modern processors to guess future instructions, allows a local attacker to potentially disclose sensitiv...
