medium Tenable Cloud Security Plugin ID 470302

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: net/sched: fix pedit partial COW
 leading to page cache corruption tcf_pedit_act() computes the COW range for skb_ensure_writable() once
 before the key loop using tcfp_off_max_hint, but the hint does not account for the runtime header offset
 added by typed keys. This can leave part of the write region un-COW'd. Fix by moving skb_ensure_writable()
 inside the per-key loop where the actual write offset is known, and add overflow checking on the offset
 arithmetic. For negative offsets (e.g. Ethernet header edits at ingress), use skb_cow() to COW the
 headroom instead. Guard offset_valid() against INT_MIN, where negation is undefined. (CVE-2026-46331)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19907.0.0 or later.
