CVE-2026-11079Network attack vector

Memory corruption via malformed video decoding

Published Jun 4, 2026 · Updated Jun 4, 2026

Improper input validation in Google Chrome before 149.0.7827.53 allows remote attackers to write outside memory bounds via a crafted video file. The Codecs component fails to validate video data before a decoding operation writes beyond an allocated memory boundary; Google has not disclosed the affected function or field. Opening or processing attacker-controlled video content is required, after which memory corruption compromises browser confidentiality, integrity, and availability.
