Out of bounds read in WebCodecs in Google Chrome prior to 146.0.7680.178 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Out-of-bounds read in WebCodecs functionality in Google Chrome prior to version 146.0.7680.178 allows remote attackers to read arbitrary memory contents via a crafted HTML page. The vulnerability affects all Chrome versions before the patched release and requires only user interaction (visiting a malicious webpage) to trigger. No public exploit code or active exploitation has been confirmed at time of analysis.
Technical ContextAI
This vulnerability exists in the WebCodecs implementation, a web standard API for encoding and decoding audio and video content in the browser. The root cause is a classic out-of-bounds read condition (CWE-125) in buffer handling within the WebCodecs subsystem. When processing specially crafted codec data embedded in an HTML page, the WebCodecs parser fails to properly validate buffer boundaries before reading memory, allowing an attacker to access data beyond the allocated buffer region. This information disclosure primitive could potentially leak sensitive data from the browser process memory, including encryption keys, session tokens, or other sensitive information resident in memory at the time of exploitation.
RemediationAI
Vendor-released patch: Google Chrome 146.0.7680.178 or later. Users should update Chrome immediately via Settings > About Google Chrome, which will automatically check for updates and apply the latest version. Enterprise administrators can accelerate rollout using Google's Chrome Enterprise deployment tools or MDM policies. Users unable to update immediately should minimize browsing to untrusted websites and avoid clicking links from untrusted sources, though this provides only partial mitigation. Refer to the official Chrome release notes at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_31.html and the Chromium issue tracker at https://issues.chromium.org/issues/491655161 for additional technical details and confirmation of the fix.
