## Technical details

A use-after-free vulnerability exists in the Ozone abstraction layer of Google Chrome. The flaw is triggered when the browser incorrectly manages memory during the processing of crafted HTML content. A remote, unauthenticated attacker can exploit this by inducing a user to visit a malicious webpage, leading to memory corruption. This corruption can be leveraged to achieve a sandbox escape, allowing for arbitrary code execution outside of the restricted browser environment. Google has addressed this issue in version 151.0.7922.72 for Windows and Mac, and 151.0.7922.71 for Linux.
