Overview

Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) via the iwlwifi process in the handling of wowlan packet lengths. An attacker can cause an underflow by supplying a crafted packet with a manipulated length field from the firmware.

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
