Remote crafted page needs no privileges (AV:N/PR:N) but a user click (UI:R); a WebGL UAF enabling sandbox escape crosses trust boundaries (S:C) with full CIA impact.

Use after free in WebGL in Google Chrome on Android prior to 151.0.7922.109 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 151.0.7922.109 stems from a use-after-free in the WebGL graphics component (CWE-416), letting a remote attacker who lures a victim to a crafted HTML page potentially break out of the renderer sandbox. Chromium rates this Critical and CVSS scores it 9.6 with a scope change (S:C), reflecting the cross-boundary sandbox escape. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Chrome WebGL memory-corruption bugs are historically high-value exploitation targets.
Technical ContextAI
WebGL is Chrome's JavaScript API for hardware-accelerated 2D/3D rendering that bridges untrusted web content to the GPU process and underlying graphics drivers. A use-after-free (CWE-416) occurs when the code continues to reference a heap object after it has been freed, allowing an attacker who controls heap allocation timing via crafted WebGL calls to reclaim the freed memory with attacker-influenced data and corrupt program state. Because WebGL command handling can cross the renderer-to-GPU trust boundary, a controllable UAF here is a plausible primitive for the scope change (S:C) reflected in the CVSS vector, i.e., a sandbox escape rather than a renderer-only compromise. The affected code path is the Android build of Chrome (Chromium/Blink WebGL implementation) prior to 151.0.7922.109.
RemediationAI
Vendor-released patch: 151.0.7922.109 - update Google Chrome for Android to 151.0.7922.109 or later via Google Play (or the Chrome auto-update mechanism) and fully restart the browser so the new binary loads. Verify the deployed version in chrome://version and, in managed fleets, push the update through MDM/enterprise policy to force rollout. Per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_01193673229.html), no supported configuration-level workaround fully removes the WebGL code path on mobile; as an interim compensating control you can steer users away from untrusted sites and, where a managed policy surface exists, disable hardware-accelerated WebGL/3D APIs to shrink the attack surface, accepting that this breaks legitimate WebGL-based sites and degrades graphics performance. Because exploitation requires user interaction, user awareness (avoid untrusted links) meaningfully reduces exposure until patching completes. Details are tracked in Chromium issue https://issues.chromium.org/issues/537729021.
