Technical Analysis
This vulnerability involves a use-after-free condition in the WebRTC implementation of Google Chrome before version 155.0.8059.39. Exploiting this flaw, a remote attacker can execute arbitrary code inside the browser's sandbox environment by delivering a specially crafted HTML page to the victim. The issue is addressed by an official patch released by Google in Chrome 155.0.8059.39.
Potential Impact
Successful exploitation can lead to remote code execution with high impact on confidentiality, integrity, and availability within the sandboxed browser process. This could allow attackers to run arbitrary code remotely without privileges, potentially compromising the affected system.
