NULL Pointer Dereference Vulnerability in Linux Kernel Affects Alienware Devices

CVE-2025-40234

What is CVE-2025-40234?

A NULL pointer dereference vulnerability in the Linux kernel affects devices that lack the Alienware Command Center (AWCC) interface. This issue occurs within sleep handlers, where the code incorrectly dereferences the 'awcc' pointer without verifying its initialization. This oversight could lead to system instability or crashes on affected devices. Proper checks must be implemented to ensure safe execution of the sleep handlers, particularly in devices that do not possess the AWCC interface.
