high Tenable Self-Hosted Container Security Plugin ID 465559

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: sch_hfsc: Fix qlen accounting bug when
using peek in hfsc_enqueue() When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the
child qdisc's peek() operation before incrementing sch->q.qlen and sch->qstats.backlog. If the child qdisc
uses qdisc_peek_dequeued(), this may trigger an immediate dequeue and potential packet drop. In such
cases, qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog have not yet been
updated, leading to inconsistent queue accounting. This can leave an empty HFSC class in the active list,
causing further consequences like use-after-free. This patch fixes the bug by moving the increment of
sch->q.qlen and sch->qstats.backlog before the call to the child qdisc's peek() operation. This ensures
that queue length and backlog are always accurate when packet drops or dequeues are triggered during the
peek. (CVE-2025-38000)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.263.24 or later.
