CVE-2026-13774 is a critical use-after-free vulnerability in the Extensions component of Google Chrome. According to the provided content, affected versions are Chrome prior to 150.0.7871.47. The flaw can be triggered via a crafted Chrome extension, and exploitation requires convincing a user to install a malicious extension. Because the bug is a use-after-free condition in a browser component that can process attacker-controlled extension content, successful exploitation may corrupt heap memory and enable control-flow hijacking, resulting in arbitrary code execution in the context of the browser process.
