About this tag
The cve 2026 19557 tag tracks coverage of a high-severity use-after-free vulnerability in Google Chrome’s TabStrip code. The reported issue affects Chrome on macOS and can enable a sandbox escape after an attacker has already compromised the browser’s renderer process, making it a potential second-stage escalation rather than a standalone drive-by takeover. Coverage focuses on Google’s fix in Chrome 151.0.7922.137 or later, along with the related Chromium security release. Microsoft Edge 151.0.4129.86, based on the patched Chromium version, is also reported as no longer vulnerable. This archive is useful for monitoring browser updates and the vulnerability’s practical security implications.
