medium Tenable Cloud Security Plugin ID 469302

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: NFSD: Fix infinite loop in layout
state revocation find_one_sb_stid() skips stids whose sc_status is non-zero, but the SC_TYPE_LAYOUT case
in nfsd4_revoke_states() never sets sc_status before calling nfsd4_close_layout(). The retry loop
therefore finds the same layout stid on every iteration, hanging the revoker indefinitely.
(CVE-2026-64519)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.3 or later.
