Impact

The flaw is an incorrect calculation inside the V8 JavaScript engine in Google Chrome versions prior to 151.0.7922.169. A crafted HTML page sent to the victim can trigger the calculation bug and cause the sandbox to be bypassed, allowing the attacker to execute arbitrary code with the privileges of the browser. This is a direct remote code execution vulnerability, involving an integer overflow (CWE-190) and an incorrect calculation (CWE-682).

Affected Systems

Google Chrome browsers on all platforms using the V8 engine and running any stable channel version older than 151.0.7922.169 are affected. The issue is limited to Chrome’s normal operation when processing HTML content; no additional components are mentioned.

Risk and Exploitability

The vulnerability has a CVSS score of 8.8, indicating high severity. The EPSS score is below 1%, indicating a low probability of exploitation, and it is not listed in the CISA KEV catalog. The likely attack vector is a crafted HTML page delivered via a browser, and exploitation requires no privileged interaction beyond normal browsing; any user who opens such a page could be compromised.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Google Chrome to version 151.0.7922.169 or newer via the built‑in updater.
  • If the automatic updater is disabled, manually download and install the latest Chrome revision from the official site.
  • Verify that the Chrome sandbox is enabled (default) and avoid executing scripts from untrusted origins; consider applying a content security policy that restricts inline scripts.
