Use-after-free in Google Chrome WebRTC
CVE-2025-10501 is a high-severity use-after-free vulnerability in the WebRTC component of Google Chrome. According to the provided content, the flaw affects Chrome versions prior to 140.0.7339.185 on Linux and prior to 140.0.7339.185/.186 on Windows and macOS. The vulnerability can be triggered by a remote attacker via a crafted HTML page, including crafted HTML/JavaScript that manipulates WebRTC state transitions, causing WebRTC to continue using memory after it has been freed. This results in heap corruption and creates conditions for further exploitation. The issue was reported by sherkito on 2025-08-23 and is rated High severity by Chromium.
