USN-8772-1: AOM vulnerabilities

Publication date

16 September 2026

Overview

Several security issues were fixed in AOM.


Packages

  • aom - AV1 Video Codec Library

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)
