critical Tenable Cloud Security Plugin ID 469398

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: pNFS: Fix use-after-free in
 pnfs_update_layout() When hitting the NFS_LAYOUT_RETURN branch in pnfs_update_layout(), the code calls
 pnfs_prepare_to_retry_layoutget(lo). If it succeeds, pnfs_put_layout_hdr(lo) is called before
 trace_pnfs_update_layout(), which still references 'lo'. This results in a use-after-free when the
 tracepoint accesses lo's fields. Fix this by moving the tracepoint call before pnfs_put_layout_hdr(lo).
 (CVE-2026-63800)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.42 or later.
