high Tenable Cloud Security Plugin ID 472193

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 packet loop on netem
 when duplicate is on When netem duplicates a packet it re-enqueues the copy at the root qdisc. If another
 netem sits in the tree the copy can be duplicated again, recursing until the stack or memory is exhausted.
 The original duplication guard temporarily zeroed q->duplicate around the re-enqueue, but that does not
 cover all cases because it is per-qdisc state shared across all concurrent enqueue paths and is not safe
 without additional locking. Use the skb tc_depth field introduced in an earlier patch: - increment it on
 the duplicate before re-enqueue - skip duplication for any skb whose tc_depth is already non-zero. This
 marks the packet itself rather than mutating qdisc state, therefore it is safe regardless of tree topology
 or concurrency. (CVE-2026-63983)

Solution

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