CVE-2026-15110 is a high-severity use-after-free vulnerability in the Extensions component of Google Chrome affecting versions prior to 150.0.7871.115. The flaw can be triggered through a crafted Chrome extension and results in heap corruption. Available reporting indicates exploitation requires convincing a user to install a malicious extension, after which the vulnerable extension-handling code may access freed memory and corrupt browser process memory. As a memory-safety flaw in a privileged browser component, the issue carries potential for further exploitation beyond a crash.
