Linux Kernel ath12k Wi-Fi Driver Use-After-Free Vulnerability

Vulnerability

A use-after-free vulnerability has been identified in the Linux kernel's Wi-Fi driver for the ath12k chipset. The issue arises in the function ath12k_dp_rx_msdu_coalesce(), where a reference to a continuation boolean is accessed after the associated memory has been freed. This improper memory access can lead to a use-after-free error, potentially allowing for exploitation.

Impact

Exploitation of this vulnerability can lead to a use-after-free condition, which may be exploited to execute arbitrary code or cause a denial-of-service condition by crashing the system.
