DescriptionCVE.org

Out of bounds write in GPU in Google Chrome on Android prior to 149.0.7827.53 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Sandbox escape in Google Chrome for Android versions prior to 149.0.7827.53 stems from an out-of-bounds write in the GPU process that a remote attacker can trigger via a crafted HTML page. Google rates the underlying Chromium issue as Critical severity, and while a vendor patch is available, no public exploit identified at time of analysis and EPSS sits at 0.03% (11th percentile). The CVSS scope-changed vector (S:C) reflects the impact of breaking out of Chrome's sandbox to affect the broader Android OS context.

Technical ContextAI

The flaw is a CWE-787 out-of-bounds write in Chrome's GPU process, which on Android handles WebGL, WebGPU, and graphics compositing on behalf of renderer processes. The GPU process sits in a privileged position relative to the renderer sandbox, so memory corruption there is a classic stepping stone for sandbox escape - the renderer feeds attacker-controlled data across the IPC boundary, and a write past an allocated buffer in GPU code can be used to hijack control flow or corrupt adjacent objects. The affected component is Chromium's GPU stack on the Android platform specifically, as called out in both the description and the EUVD entry constraining the affected build to Chrome 149.0.7827.53.

RemediationAI

Vendor-released patch: Google Chrome 149.0.7827.53 for Android - update via Google Play to the Stable channel build at or above this version (advisory: https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html). For managed Android fleets, push the update through MDM (Android Enterprise / Managed Google Play) and verify deployment status on devices. If patching is delayed, compensating controls include restricting browsing to trusted sites via enterprise URL allowlists (trade-off: breaks general web use), disabling hardware acceleration in chrome://flags to reduce GPU-process attack surface (trade-off: significant performance hit on video, WebGL, and scrolling), or steering users to an already-patched browser on the device until the rollout completes.
