Full Report
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.
Analysis Summary
# Vulnerability: Arbitrary Code Execution in Google Chrome (Type Confusion)
## CVE Details
- CVE ID: CVE-2025-13223, CVE-2025-13224 (The severe ones are listed)
- CVSS Score: Not explicitly provided (Severity indicated as high risk for large entities)
- CWE: Type Confusion (Implied by technical summary)
## Affected Systems
- Products: Google Chrome
- Versions: Prior to 142.0.7444.175/.176 for Windows and MAC; Prior to 142.0.7444.175 for Linux
- Configurations: Any user running the specified vulnerable versions. Impact is higher for users with administrative rights.
## Vulnerability Description
Multiple vulnerabilities were discovered in Google Chrome, with the most severe being related to **Type Confusion in V8**. Successful exploitation allows for **Arbitrary Code Execution (ACE)** in the context of the currently logged-on user. This means an attacker could install programs, view/modify/delete data, or create new user accounts, depending on the user's existing privileges.
## Exploitation
- Status: **Exploit exists in the wild** for CVE-2025-13223.
- Complexity: Implied Medium/High due to the requirement for Type Confusion exploitation, although the information suggests active exploitation.
- Attack Vector: Initial Access via **Drive-By Compromise** (T1189), typically requiring user interaction with a malicious website.
## Impact
- Confidentiality: Potential High (Access to user data)
- Integrity: Potential High (Data modification, program installation)
- Availability: Potential High (System compromise leading to availability loss)
## Remediation
### Patches
- Apply updates to:
- Windows/MAC: Chrome version **142.0.7444.175 or later**
- Linux: Chrome version **142.0.7444.175 or later**
*(The advisory mandates applying all appropriate updates provided by Google.)*
### Workarounds
- Apply the Principle of Least Privilege (M1026): Run software, especially web browsing, as a non-privileged user to diminish the effects of a successful attack.
- Restrict execution of code to a virtual environment (M1048).
## Detection
- Indicators of Compromise: Not explicitly detailed, but look for unusual process execution spawned by the Chrome renderer/utility process following web navigation.
- Detection Methods and Tools: Use tooling to detect and block conditions indicative of a software exploit (M1050) and ensure anti-exploitation features (DEP, SIP, etc.) are enabled (Safeguard 10.5).
