Linux Kernel AMD Display Subsystem Clock Management Vulnerability

A vulnerability in the Linux kernel's AMD display subsystem has been addressed. The issue involved an underflow condition in the Optical Timing Controller (OPTC) that was not properly cleared before turning off the Optical Display Management (ODM) clock. This oversight could lead to persistent underflow indications, potentially causing issues in clock management.

Impact

The vulnerability could disrupt proper clock management in the AMD display subsystem, leading to potential display issues or performance degradation.
