Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: Fixed the issue where percpuref does not resume after a suspend timeout. When llbitmapsuspendtimeout times out waiting for percpuref to become zero, it returns -ETIMEDOUT without resuming percpuref. The caller...

CVE-2026-45955

A flaw was found in the Linux kernel's md/md-llbitmap component. This vulnerability occurs when a suspend operation times out, failing to properly reset a critical internal reference. This oversight leaves the system's page control structure in an unusable state. This issue can lead to system...

CVE-2026-46095

CVE-2026-46095 is a Linux kernel vulnerability resolved by moving the barrier raise before the llbitmap state machine transitions. The fix updates two functions, llbitmap_start_write() and llbitmap_start_discard(), to ensure the barrier is raised prior to any state changes, preventing a race wher...

CVE-2026-46045

In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: skip reading rdevs that are not insync When reading bitmap pages from member disks, the code iterates through all rdevs and attempts to read from the first available one. However, it only checks for raiddisk...

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of the md/md-llbitmap to properly raise the barrier before state machine transitions,...

CVE-2026-46095: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: raise barrier before state machine transition Move the barrier raise operation before calling llbitmapstatemachine in both llbitmapstartwrite and llbitmapstartdiscard. This ensures the barrier is in place before a...

CVE-2026-45955: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: fix percpuref not resurrected on suspend timeout When llbitmapsuspendtimeout times out waiting for percpuref to become zero, it returns -ETIMEDOUT without resurrecting the percpuref. The caller mdllbitmapdaemonfn...

PT-2026-43822

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the md/md-llbitmap component where the llbitmap suspend timeout function returns -ETIMEDOUT upon timing out while waiting for percpu ref to reach zero, without...
