How to fix?

Upgrade torvalds/linux to version 5.10.271, 5.15.222, 6.1.189, 6.6.158, 6.12.112, 6.18.54, 7.2.8 or higher.

Overview

Affected versions of this package are vulnerable to Use After Free in the virt_wifi_newlink process. An attacker can cause memory corruption, leak sensitive kernel memory, or potentially hijack control flow by triggering the freeing of a network device object while it is still referenced in the lweventlist, then reclaiming the freed memory with controlled data and causing subsequent kernel operations to act on the manipulated object.

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
