CVE-2024-26913

Display underflow and corruption via omitted ODM calculation

Published Apr 17, 2024 · Updated May 11, 2026

Integer underflow in the AMD Display Core in Linux 6.7 through 6.7.5 allows local users to corrupt or interrupt 8K 30 Hz output. The pipe-split policy logic omits the Output Data Merger calculation, so it chooses a split configuration that cannot sustain the mode. Reachability requires a DCN35 AMD display engine and an 8K 30 Hz mode; the documented consequence is display underflow or corrupted output.
