AI Analysis

Impact

A vulnerability in the V8 JavaScript engine used by Google Chrome allows a remote attacker to perform an out‑of‑bounds write when processing a specially crafted HTML page. The flaw permits execution of arbitrary code inside a sandboxed process, effectively bypassing Chrome’s standard security boundaries. The weakness is classified as a buffer overflow (CWE‑787).

Affected Systems

Google Chrome versions prior to 148.0.7778.216 are affected. Users running these releases on any supported operating system are at risk if they open a malicious web page crafted to trigger the flaw.

Risk and Exploitability

The Chromium project rates the severity of the issue with a CVSS score of 8.8. No EPSS score is available, and the vulnerability is not listed in CISA’s KEV catalog. The likely attack vector is a user visiting a malicious site or opening a crafted HTML file; attackers can exploit this to execute code with the privileges of the Chrome sandboxed process. Because the flaw is deterministic and does not require additional exploits, it is considered highly actionable.
