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...
