CVE-2026-12455 is a high-severity use-after-free vulnerability in the Tab Strip component of Google Chrome prior to version 149.0.7827.155. The flaw can be triggered by a remote attacker using a crafted HTML page and relies on the victim performing specific user-interface gestures. The underlying condition is a stale object lifetime or dangling pointer scenario in Tab Strip handling that can lead to heap corruption after memory is reused. In affected Chromium-based browsers, successful exploitation may allow an attacker to corrupt browser memory and potentially turn the memory corruption primitive into code execution within the browser process.
