Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iouring/io-wq: The IOWQBITEXIT check is performed within the work run loop. Currently, this check is performed before running the pending work. Normally, this is completely fine, as the work items either end up blocking other tas...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: genirq/msi: The IOMMU IOVA is now stored directly in the msidesc, rather than in the iommucookie. The process of translating MSI message addresses using IOMMU involved two steps, separated in time: 1 iommudmapreparemsi: A pointer...

Astra Linux - Vulnerability in Golang-1.19

On Unix platforms, the Go runtime behaves differently when a binary is run with the setuid/setgid bits enabled. This can be dangerous in certain situations, such as when dumping memory state or assuming the status of standard I/O file descriptors. If a setuid/setgid binary is executed with standa...

CVE-2026-54533 vantage6 node has an Improper Access Control issue

vantage6 is an open-source infrastructure for privacy preserving analysis. Prior to version 5.0.0, malicious algorithms can potentially access other algorithms input and output files. Version 5.0.0 fixes the issue. As a workaround, verify and restrict the algorithm containers that are allowed to...

CVE-2026-8049

The CVE-2026-8049 issue affects SignalRGB’s Windows kernel driver, SignalIo.sys, in versions prior to 1.3.7.0. The device object (.SignalIo) is created without an explicit SDDL security descriptor and without FILE_DEVICE_SECURE_OPEN, resulting in overly permissive default access. This permits any...

Xen: x86 HVM I/O Port List Traversal (XSA-491)

HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses therefore needs...

kernel: iommu: disable SVA when CONFIG_X86 is set

A security vulnerability was found in the Linux kernel's IOMMU Shared Virtual Addressing SVA implementation on x86 architecture. When SVA is enabled, the IOMMU caches kernel page table entries. Since the kernel lacks a mechanism to notify the IOMMU when kernel page table pages are freed and...
