CVE-2022-42722
In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices.

Does this matter?
Lower severity and a low EPSS score (0.57%). Track it; it rarely justifies an emergency change on its own.
