Google Chrome GPU Heap Buffer Overflow Sandbox Escape
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An unauthenticated attacker, remotely over the network, if a user is tricked into opening a malicious file or link, can fully compromise the system — steal data, tamper with it and take it offline.

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
Until patching is applied, users should exercise extreme caution when browsing untrusted websites and avoid clicking suspicious links. Implement robust web filtering and email security solutions to reduce the likelihood of initial renderer process compromise. Organizations should also consider deploying endpoint detection and response (EDR) solutions to monitor for unusual browser process behavior or attempts at privilege escalation.
The permanent fix for this vulnerability is to promptly update Google Chrome to version 107.0.5304.121 or a later stable release. All previous versions are affected by this heap buffer overflow. Users should configure Chrome for automatic updates or manually initiate the update process via the browser's "About Chrome" section to ensure this critical vulnerability is remediated.
A remote attacker who has already compromised the browser's renderer process can exploit this heap buffer overflow in the GPU to perform a sandbox escape. This allows the attacker to break out of Chrome's security sandbox, gaining elevated privileges and potentially executing arbitrary code on the underlying operating system. The successful exploitation could lead to full system compromise, data exfiltration, or further network pivot points.
