Ubuntu Security Notice USN-5692-1

Ubuntu Security Notice 5692-1 - David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Soenke Huster discovered that an integer overflow vulnerability existed in the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A physically proximate attacker could use this to cause a denial of service or possibly execute arbitrary code.

In the Linux kernel 5.8 through 5.19.14, 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.

CVE-2022-41674: git/torvalds/linux.git - Linux kernel source tree

An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c.

CVE-2022-42719

A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.14 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code.
