CVE-2026-56211 Libaom: libaom: remote code execution via svc layer context handling with attacker-controlled frames

A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation. Insufficient bounds validation in the AV1 encoder's SVC Scalable Video Coding layer ID control allows an attacker to supply crafted video frame pixels that overlap with internal encoder layer contex...

CVE-2026-56209

CVE-2026-56209 concerns libaom’s SVC layer: a missing bounds check in the SVC layer ID control function lets an attacker inject an arbitrary pointer into the cyclic refresh map when processing frames, enabling an encoder to write about 1,200 bytes to attacker-controlled memory. This vulnerability...
