Race in Media in Google Chrome on Android prior to 147.0.7727.55 allowed a remote attacker who had compromised the renderer process to corrupt media stream metadata via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Media stream metadata corruption in Google Chrome for Android prior to 147.0.7727.55 enables remote attackers who have already compromised the renderer process to corrupt media stream metadata via a race condition (CWE-362) in the Media component. Despite a critical CVSS 9.8 score with network-accessible attack vector, real-world exploitation requires pre-compromise of the renderer, and EPSS probability is very low (0.03%, 9th percentile). Vendor patch released in Chrome 147.0.7727.55. No public exploit or active exploitation (KEV) identified at time of analysis. Chromium rates this Low severity, contrasting sharply with the theoretical CVSS rating.

Technical ContextAI

This vulnerability stems from a race condition (CWE-362) in the Media component of Google Chrome's Android implementation. Race conditions occur when multiple threads access shared resources concurrently without proper synchronization, creating time-of-check to time-of-use (TOCTOU) windows. In Chrome's architecture, the renderer process operates in a sandboxed environment isolated from system privileges. Media stream handling involves coordinating audio/video capture, processing, and delivery across thread boundaries. The race condition allows manipulation of metadata structures during concurrent access, potentially corrupting data integrity checks or object state. The CPE identifier cpe:2.3:a:google:chrome confirms this affects the Google Chrome browser application specifically on Android platforms, distinguishing it from desktop Chrome variants which may have different media pipeline implementations.

RemediationAI

Update Google Chrome for Android to version 147.0.7727.55 or later, which contains the vendor-released patch addressing the race condition in the Media component. The fix was released via Chrome's stable channel update in April 2026. Users should enable automatic updates in Chrome settings or manually update through the Google Play Store. Enterprise deployments should prioritize update rollout according to normal patch cycles given the low EPSS risk and prerequisite renderer compromise requirement. No effective workarounds exist beyond disabling media stream features entirely, which would severely impact browser functionality.
