high Tenable Cloud Security Plugin ID 466026

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: cls_u32: skip hash tables
in u32_bind_class() u32_walk() enumerates both struct tc_u_hnode and struct tc_u_knode through the walker
callback. u32_bind_class() unconditionally casts the passed fh to tc_u_knode and accesses &n->res, so when
fh is actually a tc_u_hnode, which has no tcf_result member, this results in a slab-out-of-bounds read of
res->classid in tc_cls_bind_class(). The issue can be reproduced with the following commands: tc qdisc add
dev lo root handle 1: hfsc tc class add dev lo parent 1: classid 1:1 hfsc sc rate 1000kbit tc filter add
dev lo parent 1:1 protocol ip prio 1 u32 match u32 0 0 flowid 1:1 tc class add dev lo parent 1: classid
1:2 hfsc sc rate 2000kbit Fix this by skipping hash tables via the TC_U32_KEY(handle) check.
(CVE-2026-74739)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
