Impact

Use after free in V8 within Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox by loading a crafted HTML page. The vulnerability is a classic memory corruption flaw (CWE-416) that results in execution of attacker‑supplied code within the sandboxed process.

Affected Systems

The vulnerability affects Google Chrome desktop browsers running any version earlier than 151.0.7922.72. Users on the stable channel below this revision are at risk. The affected product is the standard Chrome browser installed on Windows, macOS, and Linux.

Risk and Exploitability

The CVSS score of 8.8 indicates high severity, while the EPSS score of <1% shows that, at the time of analysis, exploitation probability is low. The vulnerability is not listed in the CISA KEV catalog. Attackers would need to deliver a malicious HTML page, likely by luring a user to visit a compromised website or opening a crafted file. Once the page is rendered, the use‑after‑free occurs during V8 parsing, allowing the attacker to run code within the sandbox.
