Heap buffer overflow in WebAudio in Google Chrome prior to 146.0.7680.165 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Unauthenticated remote attackers can exploit a heap buffer overflow in Google Chrome's WebAudio component (versions prior to 146.0.7680.165) by hosting malicious HTML pages that trigger out-of-bounds memory writes. This vulnerability enables arbitrary code execution with full system compromise potential. A patch is available from Google and Debian.
Technical ContextAI
The vulnerability resides in the WebAudio API implementation within Google Chrome (CPE: cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*), which is a complex audio processing subsystem that handles real-time audio synthesis and analysis. The root cause is classified as CWE-122 (Heap-based Buffer Overflow), indicating improper bounds checking when writing to dynamically allocated heap memory. WebAudio processes audio data through various nodes and buffers; the overflow occurs when an attacker-controlled HTML page triggers audio processing with specially crafted parameters that exceed allocated buffer boundaries. This allows memory writes beyond intended heap boundaries, a classic memory safety issue common in C++ audio libraries where manual buffer management is required.
RemediationAI
Update Google Chrome to version 146.0.7680.165 or later immediately via the browser's automatic update mechanism or by manually downloading the latest version from google.com/chrome. Chrome typically auto-updates, but users should verify they are running the patched version by navigating to chrome://settings/help. For enterprise environments where manual update control is required, deploy Chrome 146.0.7680.165+ through your standard patch management workflow. No workarounds are available to mitigate this vulnerability without patching; users running older versions should minimize browsing untrusted websites until they can update. For additional context and verification, consult the Chromium security advisory at https://issues.chromium.org/issues/485397284.
