Use after free in WebRTC in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Heap memory corruption in Google Chrome's WebRTC implementation prior to version 146.0.7680.153 enables remote attackers to execute arbitrary code by tricking users into visiting malicious websites. The use-after-free vulnerability requires only user interaction and affects Chrome on multiple platforms including Ubuntu and Debian systems. A patch is available to address this high-severity flaw.
Technical ContextAI
This vulnerability is rooted in CWE-416 (Use After Free), a memory safety issue where the WebRTC implementation in Chromium/Chrome incorrectly references memory that has already been deallocated. WebRTC is a real-time communication protocol and library stack integrated into Chrome that handles audio, video, and data channel negotiation and transmission. When WebRTC objects are freed but subsequent code paths still attempt to access them—potentially triggered by specific HTML page constructs or network signaling sequences—the freed memory may be reused by the heap allocator for other objects, resulting in corruption of unrelated data structures. This class of vulnerability is particularly dangerous in browser contexts because WebRTC runs with the privileges of the renderer process and can interact with sensitive user data and system resources. The Chromium security team classified this as High severity rather than Critical, suggesting some constraints on exploitability (e.g., may require user interaction or specific browser state), but heap corruption in a high-privilege component like WebRTC remains a serious threat vector.
RemediationAI
Immediately upgrade Google Chrome to version 146.0.7680.153 or later via the browser's built-in update mechanism (Menu > Help > About Google Chrome), which will automatically download and install the patched version. For Debian and Debian-based distributions, apply security updates to the chromium or chromium-browser package from the Debian security repository using apt update && apt upgrade, or configure automatic security updates via unattended-upgrades. For enterprise deployments, enforce Chrome version pinning to 146.0.7680.153 or higher via Group Policy (Windows), managed preferences (macOS), or browser cloud policy management. Until all systems are patched, consider restricting WebRTC functionality via Chrome policies (set webRtcUdpPortRange or disable WebRTC entirely if not required for business use), though this may break video conferencing features. Refer to the official Chrome security advisory (https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html) for patch verification and to the Chromium security commit log for detailed fix validation.
