Description Srikanth Balasubramanian 2026-08-12 07:24:53 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Use after free in TabStrip in Google Chrome on Mac prior to 151.0.7922.137 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
