Race in WebAudio in Google Chrome prior to 148.0.7778.216 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome versions prior to 148.0.7778.216 allows remote attackers to execute arbitrary code within the renderer sandbox by enticing a victim to visit a crafted HTML page that triggers a race condition in the WebAudio component. Google rates the underlying Chromium issue as High severity, and while no public exploit identified at time of analysis, the bug is browser-resident and reachable from any web origin, making it a meaningful drive-by risk once details surface. EPSS data was not provided, and the issue is not currently listed in CISA KEV.

Technical ContextAI

The flaw resides in WebAudio, the Blink/Chromium subsystem that implements the W3C Web Audio API for synthesizing and processing audio graphs inside the renderer process. The root cause is CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization, i.e. a race condition) - WebAudio uses a real-time audio thread that operates on shared AudioNode and buffer state alongside the main thread, and insufficient synchronization on those shared structures can lead to use-after-free or type confusion that an attacker grooms into arbitrary code execution. Per the CPE (cpe:2.3:a:google:chrome:*), all Chrome desktop builds before 148.0.7778.216 ship the vulnerable WebAudio code; because exploitation occurs inside the renderer, successful exploitation yields code execution constrained by the Chromium sandbox (Scope:Unchanged in the CVSS vector confirms no sandbox escape).

RemediationAI

Vendor-released patch: Google Chrome 148.0.7778.216 or later on the Stable desktop channel - update via Chrome's built-in updater (chrome://settings/help) or enterprise tooling (Chrome Browser Cloud Management, Google Update group policies) and force a relaunch so the new renderer binary is loaded, since active tabs continue running the vulnerable code until restart. Administrators of Chromium-derived browsers should track their vendor's release notes (Microsoft Edge, Brave, Opera, Electron) and roll those updates once they ship the merged WebAudio fix; reference the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html and the Chromium issue https://issues.chromium.org/issues/513750691. If patching must be deferred, compensating controls include disabling the WebAudio API via enterprise policy or site-isolation tightening, or blocking untrusted browsing through proxy/category filtering - note that disabling WebAudio breaks legitimate audio web apps (video conferencing, browser games, music tools) and site-isolation changes can increase per-tab memory overhead.
