AI Analysis

Impact

A use‑after‑free flaw exists in the Chrome updater component on Windows. The vulnerability can be triggered by a locally supplied malicious file, allowing the attacker to gain OS‑level privileges, enabling arbitrary code execution with full system rights. This high‑severity flaw is identified as CWE‑416.

Affected Systems

Google Chrome browsers installed on Windows versions prior to 150.0.7871.47 are affected. Based on the description, it is inferred that the updater runs with elevated permissions—either the actor who can inject a crafted file into the update flow can exploit the flaw.

Risk and Exploitability

The CVSS score is 7.8 and the EPSS score is < 1%, indicating a very low exploitation probability. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires local access to the target machine and delivery of a specially crafted file to the updater process, making remote exploitation unlikely. Given the privilege escalation to OS level, the attack can lead to execution of arbitrary code with system privileges, indicating high impact and therefore warrants immediate remediation.
