Impact

A use‑after‑free bug in the extension handling code of Google Chrome can corrupt heap memory when a maliciously crafted extension is installed. The flaw may result in heap corruption that could be leveraged by an attacker, potentially undermining the integrity of the browser process. The defect is identified as CWE‑416, a classic memory‑corruption weakness.

Affected Systems

Any installation of Google Chrome before version 150.0.7871.115 on any supported operating system is affected. Users who enable extensions from untrusted or malicious sources are at risk.

Risk and Exploitability

The CVSS score of 8.8 signals a high severity vulnerability if exploited. The EPSS score of less than 1% indicates a very low probability of exploitation at present, yet the condition requires a user to install a compromised extension, typically via social engineering. The issue is not listed in the CISA KEV catalog.
