CVE-2022-42721

CVE-2022-42721 is a local, WLAN-frame–triggered vulnerability in the Linux kernel mac80211/BSS handling (linked-list corruption in net/wireless/scan.c; cfg80211_add_nontrans_list) affecting 5.1–5.19.x prior to 5.19.16. Exploitation could enable code execution via crafted frames; patches exist in ...

Linux kernel 资源管理错误漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel versions 5.1 through 5.19.14, which stems from various reference counting errors handled by multiple BSSs in the mac80211 stack,...

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...

CVE-2022-42720

Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers able to inject WLAN frames to trigger use-after-free conditions to potentially execute code...
