CVE-2026-12437

Name of the Vulnerable Software and Affected Versions Google Chrome on Windows versions prior to 149.0.7827.155

Description A use-after-free issue exists in WebShare. This occurs when a program continues to use a pointer after it has been freed, which can lead to memory corruption. A remote attacker who has already compromised the renderer process can exploit this by using a crafted HTML page to potentially perform a sandbox escape, allowing code execution outside the restricted browser environment.

Recommendations Update to version 149.0.7827.155 or later.
