DescriptionCVE.org

Out of bounds write in GPU in Google Chrome on Android prior to 148.0.7778.216 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 on Android prior to 148.0.7778.216 allows remote attackers to corrupt GPU process memory via a crafted HTML page, breaking out of the renderer sandbox boundary. Chromium rates this Critical severity with a CVSS of 9.6 due to scope change, though EPSS remains low at 0.03% and no public exploit identified at time of analysis.

Technical ContextAI

The flaw resides in Chrome's GPU process, which handles hardware-accelerated rendering, WebGL, and compositing on behalf of sandboxed renderer processes. CWE-787 (Out-of-bounds Write) indicates memory corruption where the GPU component writes data past the bounds of an allocated buffer, typically due to insufficient length validation when parsing attacker-controlled graphics commands or shader inputs. Because the GPU process runs with higher privileges than the renderer sandbox in Chromium's multi-process architecture, corrupting its memory provides a path to escape the renderer's restrictive sandbox. The CPE cpe:2.3:a:google:chrome covers Chrome browser builds, with the Android platform specifically called out in the description.

RemediationAI

Vendor-released patch: Chrome for Android 148.0.7778.216 or later - update via Google Play Store or push the update through enterprise mobility management (Android Enterprise, Intune, Workspace ONE). In environments where immediate update is not feasible, compensating controls include restricting Chrome on Android to trusted-only browsing through a managed configuration, disabling hardware acceleration via the chrome://flags 'Override software rendering list' / GPU compositing flags (trade-off: significant performance and battery degradation on graphics-heavy sites and breakage of WebGL/WebGPU content), or routing traffic through a web filtering proxy that blocks known malicious domains. Refer to the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html and the Chromium bug tracker at https://issues.chromium.org/issues/505077859 for fix details.
