A heap buffer overflow in Google Chrome on Android permits potential sandbox escapes, requiring immediate version updates to maintain device security.

The vulnerability is a heap buffer overflow in the GPU process of Chrome for Android. An unauthenticated attacker who has compromised the renderer process can use a crafted HTML page to achieve a sandbox escape.

The CVSS score of 8.3 indicates a high risk of system-level compromise. On mobile devices, a sandbox escape can provide an attacker with excessive permissions, potentially leading to unauthorized access to personal data, location tracking, or the installation of malicious applications. This impact is amplified by the high frequency of mobile device usage for sensitive tasks.

Immediate Action: Update Google Chrome on all Android devices to version 149.0.7827.114 or higher via the Google Play Store.

Proactive Monitoring: Review mobile device management (MDM) reports to identify and enforce updates on non-compliant devices.

Compensating Controls: Limit the use of untrusted websites on mobile browsers and ensure that the Android OS is fully patched to support the browser's security features.

Public Exploit Available: false

Mobile security is frequently overlooked; organizations must ensure that browser updates are managed with the same urgency as desktop software. Patching this vulnerability is essential to prevent unauthorized access to mobile endpoints.
