AMD graphics driver - dynamic power management (DPM) array index validation: An unvalidated array index in the driver's

Impact

An unvalidated array index in the driver's dynamic power management functions produces an out-of-bounds access. DPM controls clocks and power states; on Instinct parts that is the machinery keeping accelerators inside their power and thermal envelope, so corruption here is worth more attention than the 3.3 score suggests even though the direct security impact is limited.

Who can reach it

Local, requires the ability to pass malformed arguments to DPM functions.

What to do

Update the AMD graphics driver and reload or reboot.
