Linux Kernel NULL Pointer Dereference Vulnerability in AMD GPU Driver

Vulnerability

A vulnerability in the Linux kernel's AMD GPU driver can lead to a NULL pointer dereference. This issue arises because certain buffer objects (BOs) may not have a backing store, resulting in a NULL resource reference. The vulnerability has been addressed by adding a NULL check before accessing the resource, preventing potential crashes or undefined behavior.

Impact

Exploitation of this vulnerability can cause a system crash or instability by dereferencing a NULL pointer, leading to a kernel panic.
