HIGH 7.5

DescriptionCVE.org

Insufficient policy enforcement in Speech in Google Chrome on Android prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to perform privilege escalation via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Privilege escalation in Google Chrome on Android before 151.0.7922.72 lets a remote attacker who has already compromised the renderer process escape further via insufficient policy enforcement in the Speech component and a crafted HTML page. Rated Medium by Chromium but scored CVSS 7.5, it enables a second-stage sandbox/privilege boundary bypass rather than initial access. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Technical ContextAI

The flaw resides in Chrome's Speech subsystem (Web Speech API / speech recognition and synthesis handling) on the Android platform. CWE-269 (Improper Privilege Management) indicates the component fails to correctly enforce policy boundaries between the sandboxed renderer and higher-privileged browser components, so a renderer that is already under attacker control can drive Speech functionality to gain privileges it should not have. The affected code is identified by cpe:2.3:a:google:chrome, but the description explicitly scopes impact to the Android build of Chrome, where the renderer sandbox and IPC surface differ from desktop.

RemediationAI

Vendor-released patch: update Google Chrome on Android to version 151.0.7922.72 or later, which is delivered through the Chrome Stable channel and Google Play; see the advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. Because Chrome auto-updates, ensure the app is not blocked from updating and force-restart the browser after update to apply it. No standalone workaround is documented; as a compensating control until updated, avoid opening untrusted web pages and consider using enterprise policy to restrict Speech/Web Speech API usage where manageable, accepting that this degrades legitimate speech-input and text-to-speech functionality. Since exploitation requires a pre-compromised renderer, keeping the browser fully patched against renderer RCE bugs is the most effective layered mitigation.
