Linux Kernel Division by Zero Vulnerability in AMD DRM/PM Component

Vulnerability

A vulnerability in the Linux kernel's AMD DRM/PM component allows for a division by zero error. This issue arises because the user can set any speed value, and if this value exceeds UINT_MAX divided by eight, it can lead to a division by zero scenario. The vulnerability was identified by the Linux Verification Center using SVACE.

Impact

Exploitation of this vulnerability causes a division by zero error, which can lead to a kernel panic or other undefined behavior.
