CVE-2023-53257 [HIGH] kernel: wifi: mac80211: check S1G action frame size
kernel: wifi: mac80211: check S1G action frame size
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: check S1G action frame size
Before checking the action code, check that it even
exists in the frame.
Statement: Exploitable by an RF-adjacent attacker via malformed 802.11ah (S1G) action frames. No local privileges required. Impact is limited to potential denial-of-service from a kernel crash. Not applicable where 802.11ah/S1G is not in use.
Fixed starting from the Red Hat Enterprise Linux 9.4.
Mitigation: To mitigate this issue, prevent module mac80211 from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
