Use after free in Core in Google Chrome on Android prior to 149.0.7827.53 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 versions prior to 149.0.7827.53 allows a remote attacker who has already compromised the renderer process to break out of the browser sandbox via a crafted HTML page. The flaw stems from a use-after-free condition in the Core component and is rated High severity by Chromium with a CVSS of 8.3. No public exploit identified at time of analysis, though the bug enables a critical post-exploitation chain step when paired with a renderer RCE.
Technical ContextAI
The vulnerability resides in the Core component of Chromium, the foundational layer underlying Chrome's rendering and browser process logic. CWE-416 (Use After Free) indicates that memory is referenced after it has been freed, allowing an attacker to manipulate the freed object - typically by reallocating controlled data at the same address - to corrupt program state, hijack control flow, or escape isolation boundaries. Because the bug is reachable from a compromised renderer and affects the Android port of Chrome (CPE-equivalent: cpe:2.3:a:google:chrome:*:*:*:*:*:android), successful exploitation crosses the renderer-to-browser-process trust boundary, which is precisely the sandbox boundary Chrome relies on to contain web-originated code.
RemediationAI
Vendor-released patch: Google Chrome for Android 149.0.7827.53 - update via Google Play Store immediately, prioritizing managed mobile devices through MDM-enforced minimum-version policies. Reference the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html and tracking issue https://issues.chromium.org/issues/506147564 for confirmation. If patching cannot be completed immediately on all devices, compensating controls include restricting Chrome on Android to known/trusted sites via enterprise URL allowlist policies (trade-off: breaks general browsing), enforcing Site Isolation (already default on Android Chrome) and Safe Browsing Enhanced Protection (modest performance/privacy trade-off), and discouraging use of Chrome on Android for sensitive workflows until patched. Disabling JavaScript globally would mitigate most renderer-side prerequisite bugs but breaks the modern web and is rarely acceptable.
