CVE-2025-40196

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw related to file system quotas. A kernel panic can occur when the panic on warn setting is enabled, specifically during writeback operations triggered by a sync call for an opened file, particularly when f2fs balancing is needed. This happens because quota release work is queued to an event queue lacking the necessary memory reclaim flag, leading to a mismatch error during f2fs balancing. The issue is resolved by creating a dedicated workqueue with the appropriate memory reclaim flag for quota release work.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
