high Tenable Cloud Security Plugin ID 469524

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: bpf: sockmap: fix tail fragment offset
 in bpf_msg_push_data When bpf_msg_push_data() inserts data in the middle of a scatterlist entry, it splits
 the original entry into a left fragment and a right fragment. The right fragment offset is page-local, but
 the code advances it with `start`, which is the message-global insertion point. For inserts into a non-
 first SG entry, this over-advances the offset and leaves the split layout inconsistent. Advance the right
 fragment offset by the fragment-local delta, `start - offset`, which matches the length removed from the
 front of the original entry. (CVE-2026-63926)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.3 or later.
