CVE-2025-68349

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

Description A flaw exists in the NFSv4/pNFS implementation where the NFS INO LAYOUTCOMMIT flag is not properly cleared in the pnfs mark layout stateid invalid function. This can lead to a crash when a layout is null during specific call stacks involving write inode and pnfs layoutcommit inode. The issue arises because pnfs set layoutcommit relies on the layout segment reference count, and failing to clear NFS INO LAYOUTCOMMIT can result in attempts to reference a null layout.

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