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: dm cache policy smq: Fix missing locks in invalidating cache blocks In passthrough mode, the invalidatemapping operation is called simultaneously by multiple workers. Therefore, it should be protected by a lock. Otherwise, we mig...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: - dm cache: Fixed the write hang issue in passthrough mode. The invalidateremove function has incomplete logic for handling write operations after cache invalidation. It sets up the remapped write operations for the overwriteb...

CVE-2026-53062

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

CVE-2026-53061

A flaw was found in the Linux kernel's device-mapper dm cache component. This vulnerability arises from an incorrect assumption that table reloads only occur after suspension, which is violated by Logical Volume Manager LVM table preloading. The dirty mapping check for passthrough mode, performed...
