Google Chrome: Integer overflow in WebGL on Android allows sandbox escape
Summary
An integer overflow in the WebGL component of Google Chrome for Android (CWE-190) allows a remote attacker to potentially execute arbitrary code outside the browser sandbox. Exploitation requires that a victim opens a crafted HTML page, so user interaction is needed, but no login is required. The vendor rates the issue as high severity and the CVSS base score is 9.6 (critical).
Affected
- Google Chrome for Android prior to 155.0.8059.39
- Chromium-based browsers on Android may inherit the flaw (not verified)
Fixed in
- Google Chrome for Android 155.0.8059.39 or later (later Android builds such as 155.0.8059.79 also include the fix)
- Desktop Debian package: 155.0.8059.39-1~deb12u1 (desktop Linux, not Android)
- Desktop build numbers for Windows and macOS are conflicting in the sources; verify against the vendor advisory
Workaround
- No vendor-documented workaround. Updating Chrome is the remediation.
- Disabling WebGL as a stopgap is unknown and not confirmed by the vendor.
Exploitation
- Not listed in CISA KEV.
- CISA SSVC: exploitation none, not automatable, technical impact total.
- Google has not stated that the vulnerability is exploited in the wild.
- No public proof of concept found.
Our recommendation
- Update Chrome on all Android phones and tablets to 155.0.8059.39 or later, including BYOD and shared devices.
- Verify the installed Chrome version on managed devices and enforce automatic updates through Google Play.
- Expect phased rollouts that may delay updates for some days; monitor until all devices are current.
- Prioritise mobile fleets with outdated Chrome versions.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
