Multiple Vulnerabilities in Google Chrome Could Allow for Arbitrary Code Execution

📅 12 August 2026 at 15:16 UTC📰 CIS AdvisoriesView original source ↗

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for arbitrary code execution. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
