CVE-2024-46850

CVE-2024-46850 affects the Linux kernel DRM/AMD display path: the dcn35_set_drr() function in the AMD DC hardware sequencing code can race with dc_state_destruct() which nulls the DC state resource context. If destruction occurs in parallel with IRQ processing that calls dcn35_set_drr(), callback...
