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...
