Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.85.5

high Tenable Self-Hosted Container Security Plugin ID 450615

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: wireguard: netlink: check for dangling
peer via is_dead instead of empty list If all peers are removed via wg_peer_remove_all(), rather than
setting peer_list to empty, the peer is added to a temporary list with a head on the stack of
wg_peer_remove_all(). If a netlink dump is resumed and the cursored peer is one that has been removed via
wg_peer_remove_all(), it will iterate from that peer and then attempt to dump freed peers. Fix this by
instead checking peer->is_dead, which was explictly created for this purpose. Also move up the
device_update_lock lockdep assertion, since reading is_dead relies on that. It can be reproduced by a
small script like: echo "Setting config..." ip link add dev wg0 type wireguard wg setconf wg0 /big-config
( while true; do echo "Showing config..." wg showconf wg0 > /dev/null done ) & sleep 4 wg setconf wg0
<(printf "[Peer]\nPublicKey=$(wg genkey)\n") Resulting in: BUG: KASAN: slab-use-after-free in
