CVE-2024-46772

Kernel crash via unchecked crb_pipes divisor

Published Sep 18, 2024 · Updated May 11, 2026

Divide-by-zero in the AMD display DCN 3.15 resource path in Linux allows local users to crash the kernel through display processing. The dcn315_populate_dml_pipes_from_context function divides and takes a remainder by crb_pipes while distributing remaining detile-buffer segments without first rejecting a zero value. Reachability requires the DCN 3.15 AMD display path and local low-privileged access; no data disclosure or modification is reported.
