Impact

A vulnerability in Google Chrome on Android allows an out of bounds write in the WebGL component to be exploited by a maliciously crafted HTML page, potentially giving a remote attacker the ability to escape the browser sandbox and execute arbitrary code within the device’s operating system. This is a memory corruption weakness classified as CWE‑787.

Affected Systems

Android devices running Google Chrome versions prior to 151.0.7922.72 are affected. Any Android device that has not applied the 151.0.7922.72 or newer Chrome release is vulnerable.

Risk and Exploitability

The CVSS score of 9.6 classifies this as critical severity, but the EPSS score of less than 1% indicates a very low likelihood of exploitation as of the current data. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Based on the description, the likely attack vector is a crafted HTML page that the user views in Chrome, which then triggers the out of bounds write leading to a sandbox escape.
