A use-after-free vulnerability in Google Chrome on Mac prior to version 148.0.7778.96 allows remote attackers to execute arbitrary code via a crafted HTML page.

This is a use-after-free vulnerability (CWE-416) residing in the Audio component of the browser. An unauthenticated remote attacker can trigger this flaw through user interaction by enticing a victim to visit a crafted HTML page.

A successful exploit can lead to complete system compromise, allowing an attacker to execute arbitrary code within the context of the user session. This poses severe risks to data confidentiality, integrity, and availability. Although the CVSS score is 8.8, indicating high severity, exploitation requires user interaction to visit a malicious page.

Immediate Action: Update Google Chrome on Mac to version 148.0.7778.96 or later as provided by the vendor security advisory.

Proactive Monitoring: Monitor endpoint telemetry for anomalous browser subprocess crashes or unexpected child process spawning events.

Compensating Controls: Implement secure web gateway filtering to block access to known malicious domains and employ browser security policies to restrict untrusted script execution.

Public Exploit Available: No (False)

Given the high severity score and potential for remote code execution, organizations must prioritize updating Google Chrome instances on all managed Mac endpoints immediately. Applying the vendor patch is the only definitive method to remediate the underlying memory corruption flaw.
