Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.521.55

medium Tenable Cloud Security Plugin ID 451079

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: sch_qfq: Fix null-deref in
agg_dequeue To prevent a potential crash in agg_dequeue (net/sched/sch_qfq.c) when
cl->qdisc->ops->peek(cl->qdisc) returns NULL, we check the return value before using it, similar to the
existing approach in sch_hfsc.c. To avoid code duplication, the following changes are made: 1. Changed
qdisc_warn_nonwc(include/net/pkt_sched.h) into a static inline function. 2. Moved qdisc_peek_len from
net/sched/sch_hfsc.c to include/net/pkt_sched.h so that sch_qfq can reuse it. 3. Applied qdisc_peek_len in
agg_dequeue to avoid crashing. (CVE-2025-40083)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.521.55 or later.
