Code execution via undisclosed out-of-bounds write
Published Mar 9, 2022 · Updated May 27, 2026
Out-of-bounds write in Microsoft VP9 Video Extensions before 1.0.42791.0 allows context-dependent attackers to execute code. Microsoft has not disclosed the affected decoding routine, the untrusted VP9 field involved, or the operation that writes beyond its destination buffer. The published CVSS assessment requires user interaction and local attack conditions, limiting exposure to systems that process attacker-controlled VP9 content.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
