Out of bounds read in WebGL 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 potentially break out of the renderer sandbox via an out-of-bounds read in the WebGL component when a victim visits a crafted HTML page. Chromium rates the underlying issue as Critical severity, and while no public exploit is identified at time of analysis (EPSS 0.03%), the combination of scope-change (S:C) and full CIA impact makes this a high-priority browser patch for Android fleets.
Technical ContextAI
The flaw resides in WebGL, the JavaScript API that Chrome exposes to web content for hardware-accelerated 3D graphics via the GPU process. CWE-125 (Out-of-bounds Read) here means specially-crafted WebGL state or buffers cause the renderer to read memory outside an allocated buffer; in the context of Chrome's multi-process model, an OOB read in WebGL can leak addresses or pointers needed to chain into a sandbox escape from the GPU/renderer process. Affected CPE is cpe:2.3:a:google:chrome on the Android platform, where the GPU sandbox boundary historically differs from desktop and has been a recurring target for chain exploits.
RemediationAI
Vendor-released patch: Chrome for Android 148.0.7778.216 - update via Google Play Store or managed enterprise deployment per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop_0877304591.html. Where immediate patching is not feasible, a workable compensating control is to disable WebGL on Android Chrome through enterprise policy (HardwareAccelerationModeEnabled / chrome://flags WebGL toggles) or by routing browsing through a policy that blocks untrusted sites; the trade-off is broken rendering on legitimate 3D/canvas-heavy sites and degraded performance. Network-layer mitigations (web filtering / browser isolation for high-risk users) reduce exposure but do not address the root cause and add latency and cost.
