Stack buffer overflow in WebRTC in Google Chrome prior to 146.0.7680.153 allowed a remote attacker to potentially exploit stack corruption via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Stack buffer overflow in Google Chrome's WebRTC implementation prior to version 146.0.7680.153 enables remote attackers to corrupt stack memory and achieve code execution through maliciously crafted HTML pages. The vulnerability affects Chrome, and potentially downstream products including Chromium-based browsers, requiring only user interaction and no authentication. A patch is available across affected platforms including Ubuntu and Debian.
Technical ContextAI
This vulnerability is a classic stack buffer overflow (CWE-121) occurring within Chrome's WebRTC implementation, which handles real-time communication protocols and media streaming. WebRTC processes untrusted input from network sources and HTML content; insufficient bounds checking on stack-allocated buffers allows an attacker to write beyond allocated memory boundaries. The root cause falls under CWE-121 (Stack-based Buffer Overflow), indicating that local stack variables were not properly validated before being written to. The affected product is Google Chrome (identified by Chromium project tracking), and the vulnerability impacts the WebRTC subsystem which is critical for video/audio conferencing features in modern web applications.
RemediationAI
Users should immediately upgrade Google Chrome to version 146.0.7680.153 or later, which includes the fix for this stack buffer overflow. The official security update is available through Chrome's automatic update mechanism and documented at https://chromereleases.googleblog.com/2026/03/stable-channel-update-for-desktop_18.html. Enterprise administrators should deploy this update via their standard Chrome update mechanisms (Google Update, Intune, managed rollouts, or equivalent). For systems unable to patch immediately, restrict users from accessing untrusted websites by implementing URL filtering and content security policies; however, this is not a substitute for patching. Debian users should update their chromium or chromium-browser packages to the patched versions corresponding to their distribution release.
