Overview

Affected versions of this package are vulnerable to Use After Free in the ieee80211_prepare_and_rx_handle process. An attacker can cause kernel memory corruption or disclosure of sensitive information by sending specially crafted mesh data frames over WiFi that trigger use of freed memory during RX processing.

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
