CVE-2024-57922

Local system crash via zero display granularity

Published Jan 19, 2025 · Updated May 11, 2026

Divide-by-zero in the Linux kernel AMD display bandwidth code allows local users to crash the system through crafted display parameters. The dcn_bw_ceil2 and dcn_bw_floor2 wrappers pass zero granularity into helpers that assert and divide by that value. A low-privileged local user must reach the AMD display-mode calculation path; the reported impact is a system crash, not data disclosure or modification.
