critical Tenable Cloud Security Plugin ID 467045

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: bridge: stop fast-leave after
deleting a port group br_multicast_leave_group() iterates mp->ports with pp = &p->next in its fast-leave
path. After br_multicast_del_pg() removes p, continuing the loop advances pp through the deleted entry. If
multicast-to-unicast was enabled, the bridge can hold multiple port groups for the same port and group
with different source MAC addresses. Once multicast-to-unicast is disabled, br_port_group_equal() matches
those entries by port only. A fast leave can then delete one entry and continue from its stale next
pointer, leaving mp->ports pointing at a deleted port group. Fast leave only needs to remove one matching
port group. Break after br_multicast_del_pg() so the loop stops before dereferencing the removed entry.
(CVE-2026-74480)

Solution

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