Description

A flaw was found in the Linux kernel's AMD display (drm/amd/display) component. An issue occurs when the physical layer's finite state machine (PHY FSM) incorrectly transitions during the disabling of Transition Minimized Differential Signaling (TMDS) output on DCN35 hardware. This can cause the Output Timing Generator (OTG) to become stuck, leading to a system hang and a denial of service.
