Summary
aom vulnerabilities
Details

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 AOM incorrectly validated spatial and temporal layer IDs in the SVC (Scalable Video Coding) encoder controls. An attacker could possibly use this issue to write to an arbitrary memory address, read out-of-bounds heap memory, or execute arbitrary code. (CVE-2026-56209, CVE-2026-56210, CVE-2026-56211)
