Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm/hugememory: The issue of “folio not being locked” in softleaftofolio has been fixed. On the arm64 server, we found that the “folio” data obtained from the migration entries is not properly locked in softleaftofolio. This issue...

kernel: mm/khugepaged: write all dirty file folios when collapsing

A flaw was found in the Linux kernel's memory management mm/khugepaged component. A local user could trigger an edge case where unsaved changes to file data dirty folios are improperly discarded. This occurs when a file with previous writes is subjected to a specific sequence of memory advice...

CVE-2026-89758

A flaw was found in the Linux kernel's memory management subsystem. When an HMM-based Graphics Processing Unit GPU driver migrates a Transparent Huge Page THP to device memory, it can leave a device-private Page Middle Directory PMD entry. If a user-space application then attempts to manage this...
