Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 86.0.4240.183

Description The issue is a stack buffer overflow in WebRTC, which could allow a remote attacker to exploit stack corruption via a crafted WebRTC packet. This could potentially impact the confidentiality, integrity, and availability of protected information.

Recommendations For versions prior to 86.0.4240.183, update to version 86.0.4240.183 or later to resolve the issue. As a temporary workaround, consider disabling WebRTC functionality until a patch is applied. Restrict access to WebRTC packets to minimize the risk of exploitation. Avoid using crafted WebRTC packets in affected API endpoints until the issue is resolved.
