AI Analysis

Impact

Chrome’s V8 JavaScript engine contains an out‑of‑bounds read and write bug that can be triggered from a specially crafted HTML page. The flaw permits a remote attacker to read or corrupt memory beyond intended bounds and thereby execute arbitrary code inside the browser’s sandbox. This could allow an attacker to execute arbitrary code within the sandbox.

Affected Systems

All users running Google Chrome versions earlier than 150.0.7871.128 are vulnerable. The issue has been fixed in Chrome 150.0.7871.128 and later releases.

Risk and Exploitability

The CVSS score of 8.8 reflects a high impact due to remote code execution. The EPSS value is below 1 %, indicating a low likelihood of attack at this time, and the vulnerability is not catalogued in CISA’s KEV. Attackers would need to supply a malicious HTML page that is rendered by the victim’s browser, making the vulnerability exploitable over the network through a normal browsing channel. The lack of a publicly known exploit, combined with the low EPSS, suggests the risk is moderated but the damage potential remains high.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Chrome to version 150.0.7871.128 or newer, which contains the V8 fix.
  • Ensure that automatic updates are enabled so future patches are applied promptly.
  • If an upgrade cannot be performed immediately, restrict the use of untrusted HTML content and consider disabling JavaScript for sensitive sites as a temporary measure.
