critical Tenable Self-Hosted Container Security Plugin ID 469374

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 SECINFO_NO_NAME decode error
 cleanup nfsd4_decode_secinfo_no_name() currently initializes sin_exp after decoding sin_style. If the XDR
 stream is truncated, the decoder returns nfserr_bad_xdr before sin_exp is initialized. Since commit
 3fdc54646234 ("NFSD: Reduce amount of struct nfsd4_compoundargs that needs clearing"), the inline iops
 array is not cleared between RPC calls. A failed SECINFO_NO_NAME decode can therefore leave sin_exp
 holding stale union contents from a previous operation. The error response path still invokes
 nfsd4_secinfo_no_name_release(), which calls exp_put() on a non-NULL sin_exp. Initialize sin_exp before
 the first failable decode step, matching nfsd4_decode_secinfo(). (CVE-2026-53398)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.60 or later.
