Описание
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.
A use-after-free flaw was found in ieee802_11_parse_elems_full in the net/mac80211/util.c function in the multi-BSSID element. This issue occurs while parsing in the Linux kernel.
Отчет
There was no shipped kernel version that was seen affected by this problem.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
