high Tenable Self-Hosted Container Security Plugin ID 472686

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 nfsd_file leak on inter-
 server COPY setup failure When nfsd4_setup_inter_ssc() fails, nfsd4_copy() returns nfserr_offload_denied
 directly, bypassing the out: label where release_copy_files() would drop the nf_dst reference taken by
 nfs4_preprocess_stateid_op(). Each failed inter-server COPY leaks one nfsd_file, pinning
 file/inode/dentry/vfsmount. Fix by setting status and jumping to out: instead of returning directly.
 (CVE-2026-89680)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.505.8 or later.
