Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: mm/hugememory: Fixed the issue of dereferencing an invalid PMD migration entry. When migrating a THP, concurrent access to the PMD migration entry during a deferred split scan can lead to an invalid address access, as illustrated...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: mm: hugememory: use !CONFIG64BIT to relax huge page alignment on 32-bit machines Yves-Alexis Perez reported a commit 4ef9ad19e176 “mm: hugememory: don’t force huge page alignment on 32-bit machines” which did not work for x8632 1...
kernel: mm/huge_memory: update file PMD counter before folio_put()
A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...
AZL-97292 CVE-2026-74672 affecting package kernel for versions less than 6.6.157.1-1
In the Linux kernel, the following vulnerability has been resolved: mm/vmalloc: acquire initmm lock on huge vmap to avoid ptdump UAF Patch series "mm: fix UAF caused by race between ptdump and vmap pgtable freeing", v6. Kernel page table walkers fall into two broad categories - those ranges where...
CVE-2026-74672: Undefined Security Weakness

Kernel page table walkers fall into two broad categories - those ranges where...
CVE-2026-74518
A flaw was found in the Linux kernel. The allocatefileregionentries function, responsible for managing huge page memory regions, can suffer from list corruption. This occurs because the listsplice operation does not properly re-initialize a list head, allowing concurrent access to shared memory...
