CRITICAL 9.6

DescriptionCVE.org

Insufficient validation of untrusted input in Dawn in Google Chrome on Android prior to 151.0.7922.72 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 before 151.0.7922.72 stems from insufficient input validation in Dawn, Chromium's WebGPU implementation, and allows a remote attacker who lures a victim to a crafted HTML page to potentially break out of the renderer/GPU-process sandbox (CVSS 9.6, scope-changed). There is no public exploit identified at time of analysis and the flaw is not in CISA KEV; EPSS is low at 0.31% (23rd percentile), consistent with SSVC rating exploitation as 'none' despite a 'total' technical impact. Chrome rates the underlying Chromium bug as Critical.

Technical ContextAI

Dawn is Chromium's cross-platform implementation of the WebGPU standard, providing web pages low-level access to GPU compute and rendering through the browser's GPU process. Because WebGPU exposes a large, complex attack surface that parses and acts on richly structured, attacker-controllable command data, a CWE-20 (Improper Input Validation) defect here means untrusted input from a web page is not adequately checked before use, which can corrupt GPU-process state. The scope-changed CVSS metric (S:C) and 'sandbox escape' framing indicate the impact crosses the renderer/GPU sandbox boundary into a more privileged context. The single affected CPE is cpe:2.3:a:google:chrome, with the described impact specific to the Android build prior to 151.0.7922.72.

RemediationAI

Vendor-released patch: update Google Chrome on Android to 151.0.7922.72 or later via the Google Play Store, which is the primary and recommended fix; this should apply automatically for most managed and consumer devices but should be verified in enterprise fleets. Reference the Chrome release note at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html and the NVD entry https://nvd.nist.gov/vuln/detail/CVE-2026-17651. If patching cannot be completed immediately, a targeted compensating control is to disable WebGPU (the Dawn attack surface) via the chrome://flags 'Unsafe WebGPU' / WebGPU flags or enterprise policy where available - trade-off: this breaks GPU-accelerated web apps and games that rely on WebGPU. As a broader stopgap, restrict browsing on unpatched Android devices to trusted sites, since exploitation requires the victim to load a crafted page.
