Analysis

Impact

Use‑after‑free error in Chrome’s WebProtect module exists in versions before 150.0.7871.47. An attacker can trigger the freed memory to execute arbitrary code with the same privileges as the browser, allowing the attacker to run code, potentially compromising the user’s machine or data.

Affected Systems

Google Chrome versions earlier than 150.0.7871.47 are affected. The CVE data does not list specific operating systems, so the scope of affected platforms is unspecified.

Risk and Exploitability

Chromium labels the issue as low severity, but the attack requires the user to install a malicious extension, making it a social‑engineering scenario. The CVSS score of 8.1 indicates high severity, while the EPSS score of <1% indicates very low exploitation probability. The vulnerability is not listed in the CISA KEV catalog, indicating it has not been observed in the wild as a delivered exploit.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Update Google Chrome to version 150.0.7871.47 or later to eliminate the use‑after‑free fault (CWE-416).
Configure the browser to restrict extension installation only to the Chrome Web Store, preventing social‑engineering delivery of malicious extensions.
Disable all user‑installed extensions until the browser is updated to mitigate the use‑after‑free risk.
