CVE-2026-5902Network attack vector

Media metadata corruption via race condition

Published Apr 8, 2026 · Updated Apr 8, 2026

Race condition in Media in Google Chrome before 147.0.7727.55 allows remote attackers to corrupt media stream metadata. Google has not publicly identified the Media code locus or unsynchronized operations because the linked issue remains restricted. Exploitation requires a crafted HTML page in a renderer process that the attacker has already compromised, and the reported consequence is limited to metadata corruption.
