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: bonding: alb: fix UAF in rlb_arp_recv
during bond up/down The ALB RX path may access rx_hashtbl concurrently with bond teardown. During rapid
bond up/down cycles, rlb_deinitialize() frees rx_hashtbl while RX handlers are still running, leading to a
null pointer dereference detected by KASAN. However, the root cause is that rlb_arp_recv() can still be
accessed after setting recv_probe to NULL, which is actually a use-after-free (UAF) issue. That is the
reason for using the referenced commit in the Fixes tag. [ 214.174138] Oops: general protection fault,

do_softirq+0xb1/0xf0 [ 214.439830] </IRQ> The issue is reproducible by repeatedly running ip link set
bond0 up/down while receiving ARP messages, where rlb_arp_recv() can race with rlb_deinitialize() and
dereference a freed rx_hashtbl entry. Fix this by setting recv_probe to NULL and then calling
synchronize_net() to wait for any concurrent RX processing to finish. This ensures that no RX handler can
access rx_hashtbl after it is freed in bond_alb_deinitialize(). (CVE-2026-45970)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.5 or later.
