Use after free in WebRTC in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Remote code execution in Google Chrome's WebRTC component (versions prior to 148.0.7778.96) allows attackers to execute arbitrary code within the browser's sandbox by exploiting a use-after-free memory corruption vulnerability via a malicious HTML page. While sandboxed, successful exploitation achieves high confidentiality, integrity, and availability impact within the renderer process. EPSS data unavailable; not listed in CISA KEV, indicating no confirmed widespread exploitation at time of analysis. Vendor patch released as Chrome 148.0.7778.96.
Technical ContextAI
This vulnerability affects the WebRTC (Web Real-Time Communication) implementation in Chrome, specifically the media streaming and peer-to-peer communication framework. WebRTC enables browser-based audio, video, and data sharing without plugins. The root cause is CWE-416 (Use After Free), a memory corruption class where code attempts to access memory after it has been freed. In Chrome's multi-process architecture, WebRTC runs within the renderer sandbox, which limits the impact of successful exploitation by preventing direct system access. The CPE string cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* indicates all Chrome distributions are potentially affected prior to the patched version. Use-after-free vulnerabilities in browser components typically arise from improper object lifecycle management during complex asynchronous operations common in real-time communication protocols.
RemediationAI
Update Google Chrome to version 148.0.7778.96 or later immediately. Chrome's automatic update mechanism typically deploys patches within days for most users, but enterprise deployments should verify update completion through management consoles. For Windows/Mac/Linux desktop: Navigate to chrome://settings/help to trigger immediate update check and installation. For managed enterprise deployments: Push Chrome 148.0.7778.96 via group policy or mobile device management systems. For Android: Update via Google Play Store. For iOS: Update via App Store. Detailed release information available at http://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html. If immediate patching is not feasible, implement compensating controls: disable WebRTC entirely via chrome://flags/#disable-webrtc (breaks legitimate video conferencing and reduces functionality significantly), enforce strict content security policies to limit untrusted HTML content execution, or restrict browser access to only trusted domains via enterprise policies (may impact business operations requiring broad web access). No effective workaround exists that maintains full WebRTC functionality while mitigating this specific use-after-free vulnerability.
