CVE-2024-7977

Local privilege escalation via malicious installer file

Published Aug 21, 2024 · Updated Aug 22, 2024

Improper input validation in Google Chrome Installer before 128.0.6613.84 on Windows allows local users to escalate privileges via a malicious file. Google has not disclosed the Installer code path or the validation operation that mishandles the file because the underlying issue remains access-restricted. Exploitation requires local execution and user interaction with the malicious file; success elevates privileges, but the resulting privilege boundary is undisclosed.
