Heap buffer overflow in GPU in Google Chrome on Android prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Sandbox escape in Google Chrome on Android prior to 149.0.7827.103 allows a remote attacker who has already compromised the renderer process to break out of Chrome's sandbox via a heap buffer overflow in the GPU process triggered by a crafted HTML page. Rated High severity by Chromium with a CVSS 8.3 reflecting scope change and full CIA impact; no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Technical ContextAI
The flaw is an out-of-bounds write (CWE-787) in Chrome's GPU process on Android. The GPU process is a privileged Chromium component that brokers hardware-accelerated rendering for the sandboxed renderer; memory corruption there is a classic pivot for sandbox escapes because the GPU process runs at a higher privilege than the renderer. The crafted HTML page presumably reaches a GPU command or shader-handling path (e.g., WebGL/Skia/ANGLE-style surfaces) that mishandles heap buffer sizing, enabling controlled writes beyond an allocation. Chromium tracker issues.chromium.org/issues/516794471 and the Chrome Releases advisory document the fix in 149.0.7827.103.
RemediationAI
Vendor-released patch: Chrome for Android 149.0.7827.103 - upgrade via Google Play to that version or later as documented in the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html. For managed Android fleets, push the update through MDM/Managed Google Play and verify chrome://version on a sample of devices; for enterprise users on Chrome Browser Cloud Management, confirm the auto-update rollout has reached affected endpoints. No vendor-documented workaround exists for the GPU flaw itself, but because exploitation requires a prior renderer compromise, interim compensating controls include restricting browsing to trusted origins via enterprise URL allowlists, disabling unnecessary GPU-accelerated features such as WebGL through the 'Disable3DAPIs' policy (trade-off: breaks WebGL-dependent sites and degrades rendering performance), and enabling Site Isolation and Strict Site Isolation policies if not already on by default.
