LIN1025-6980 : Security Advisory - linux - CVE-2025-68349

Created: Dec 25, 2025 Updated: Dec 27, 2025

Found In Version: 10.25.33.2

Severity: Standard

Applicable for: Wind River Linux LTS 25

Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

NFSv4/pNFS: Clear NFS_INO_LAYOUTCOMMIT in pnfs_mark_layout_stateid_invalid

Fixes a crash when layout is null during this call stack:

write_inode
    -> nfs4_write_inode
        -> pnfs_layoutcommit_inode

pnfs_set_layoutcommit relies on the lseg refcount to keep the layout
around. Need to clear NFS_INO_LAYOUTCOMMIT otherwise we might attempt
to reference a null layout.
