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: netfilter: IDLETIMER: Fix for possible
 ABBA deadlock Deletion of the last rule referencing a given idletimer may happen at the same time as a
 read of its file in sysfs: | ====================================================== | WARNING: possible
 circular locking dependency detected | 6.12.0-rc7-01692-g5e9a28f41134-dirty #594 Not tainted |
 ------------------------------------------------------ | iptables/3303 is trying to acquire lock: |
 ffff8881057e04b8 (kn->active#48){++++}-{0:0}, at: __kernfs_remove+0x20 | | but task is already holding
 lock: | ffffffffa0249068 (list_mutex){+.+.}-{3:3}, at: idletimer_tg_destroy_v] | | which lock already
 depends on the new lock. A simple reproducer is: | #!/bin/bash | | while true; do | iptables -A INPUT -i
 foo -j IDLETIMER --timeout 10 --label "testme" | iptables -D INPUT -i foo -j IDLETIMER --timeout 10
 --label "testme" | done & | while true; do | cat /sys/class/xt_idletimer/timers/testme >/dev/null | done
 Avoid this by freeing list_mutex right after deleting the element from the list, then continuing with the
 teardown. (CVE-2024-54683)
