Process crash via LAP stats buffer overflow
Published Jun 19, 2026 · Updated Jun 19, 2026
Heap buffer overflow in libaom before 3.14.0 allows remote attackers to crash an encoding process through LAP-mode encoding. The first-pass statistics ring buffer uses a wrap-around guard that LAP mode bypasses when g_lag_in_frames is at least 1, causing a 232-byte out-of-bounds write after the second frame. Reachability requires an application to expose attacker-influenced encoder configuration; adjacent heap corruption creates a code-execution path whose feasibility depends on control over encoder-computed values.
