Linux Kernel Remote Code Execution Vulnerability (CVE-2022-42721)
A remote code execution vulnerability (CVE-2022-42721) affecting Linux kernel versions 5.1 through 5.19.14 allows local attackers to inject malicious WLAN frames that corrupt the mac80211 BSS handling list, enabling execution of arbitrary code, and can be mitigated by upgrading to kernel 5.19.15 or later.
The Linux kernel is a free, open‑source Unix‑like operating system kernel.
Versions 5.1 to 5.19.14 contain a remote code execution (RCE) vulnerability caused by improper handling of the BSS processing list in the mac80211 stack; a local attacker can inject crafted WLAN frames to corrupt the linked list and trigger execution of malicious code.
