USN-8772-1: AOM vulnerabilities

It was discovered that AOM incorrectly handled the first-pass statistics buffer in Look-Ahead Processing LAP mode. An attacker could possibly use this issue to cause a heap buffer overflow, leading to a denial of service or possibly execute arbitrary code. CVE-2026-56208 It was discovered that AO...

libaom: libaom: heap buffer overflow in AV1 encoder first-pass stats buffer via LAP mode

A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing LAP mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when glaginframes is set to 1 or higher. This results in a 232-byte...

CVE-2026-56208

CVE-2026-56208 affects libaom, the reference AV1 codec. A flaw in the encoder’s Look-Ahead Processing (LAP) mode bypasses the first-pass stats ring-buffer guard when g_lag_in_frames is 1 or more, causing a 232-byte out-of-bounds write on every frame after the second. This can corrupt heap objects...
