Remote crafted page needs only a visit (UI:R) with no auth (PR:N); sandbox escape crosses a trust boundary (S:C) and code execution yields full C/I/A impact.

Out of bounds write in WebGL in Google Chrome on on Android prior to 153.0.8010.36 allowed a remote attacker to execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Remote code execution in Google Chrome for Android prior to 153.0.8010.36 arises from an out-of-bounds write in the WebGL graphics subsystem, letting a remote attacker who lures a user to a crafted HTML page execute arbitrary code outside the renderer sandbox. Rated Critical by Chromium and CVSS 9.6, the scope-changed vector reflects a full sandbox escape. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open an attacker-controlled HTML page in Google Chrome for Android older than 153.0.8010.36 (UI:R - user interaction to visit/render the page), after which no authentication is needed (PR:N, unauthenticated). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine priority rather than an inflated high-CVSS score: the CVSS 9.6 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H) is corroborated by an independent Chromium 'Critical' severity rating, and the described impact - arbitrary code execution outside the sandbox - is the most severe outcome for a browser bug. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update Google Chrome for Android to 153.0.8010.36 or later (Vendor-released patch: 153.0.8010.36), as announced in the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html); Chrome normally auto-updates, so ensure devices are allowed to fetch the update and restart the browser to apply it, and in managed Android fleets push the update via MDM/Play Managed configuration and verify the effective version. … Detailed patch versions, workarounds, and compensating controls in full report. |
