Overview

Affected versions of this package are vulnerable to Buffer Overflow in the sta_remove_link process. An attacker can corrupt kernel memory and potentially execute arbitrary code or cause a denial of service by triggering a race condition between the removal of a link and the freeing of its associated percpu RX stats buffer, leading to use of freed memory. This is only exploitable if the system is using a mainstream RSS-capable MLO driver and the attacker is within Wi-Fi range to inject malicious frames.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
