## Technical details

A use-after-free vulnerability exists in the Sharing component of Google Chrome on iOS versions prior to 153.0.8010.36. The vulnerability allows an attacker to send crafted network traffic that triggers a use-after-free condition, enabling arbitrary code execution outside the sandbox boundary. The attack requires network access and no user authentication, though it may require user interaction with a malicious web page or link. Successful exploitation grants an attacker arbitrary code execution with the privileges of the Chrome process, potentially leading to full device compromise.
