Description

A flaw was found in the Linux kernel's AMD display (drm/amd/display) driver. A race condition can occur when the dc_state_destruct() function is called concurrently with interrupt (IRQ) processing. This can lead to the dcn35_set_drr() function attempting to use already cleared resource fields, potentially causing a system crash and resulting in a Denial of Service (DoS).
