CVE-2022-42719
A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.x before 5.19.16 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
