CVE-2025-38393

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

Description A race condition exists in the NFSv4/pNFS implementation that can lead to system hangs during writeback operations. The issue occurs when waiting on the NFS LAYOUT DRAIN bit in pnfs update layout(), potentially due to a race between the waiter and waker similar to a previously identified synchronization issue. Applying an advised barrier resolves the race condition.

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