Full Report
A Vulnerability has been discovered in Google Chrome which could allow for arbitrary code execution. Successful exploitation of the the vulnerability 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 via Use After Free
## CVE Details
- CVE ID: CVE-2025-8292
- CVSS Score: Score not explicitly provided, but the impact suggests a **High** severity rating for environments with administrative users.
- CWE: Use After Free (in Media Stream component)
## Affected Systems
- Products: Google Chrome
- Versions: Prior to 138.0.7204.183/.184 for Windows and Mac; Prior to 138.0.7204.183 for Linux
- Configurations: Applicable to all installations running vulnerable versions, with severity impact dependent on user privilege levels.
## Vulnerability Description
A Use After Free vulnerability exists within the Media Stream component of Google Chrome. Successful exploitation allows an attacker to execute arbitrary code in the context of the currently logged-on user. If the user possesses administrative privileges, the attacker can install programs, modify or delete data, or create new accounts with full user rights. Less privileged users face a diminished impact.
## Exploitation
- Status: No threat intelligence of exploitation in the wild reported. PoC availability is **Unknown/Not Stated**.
- Complexity: Implied to be achievable via Technique T1189 ("Drive-By Compromise"), suggesting relative ease if the user visits a malicious source.
- Attack Vector: Likely **Network** (via a malicious webpage triggering the flaw).
## Impact
- Confidentiality: High (If exploited by an admin user)
- Integrity: High (If exploited by an admin user)
- Availability: Medium (Potential for service disruption depending on payload)
## Remediation
### Patches
- Google Chrome version **138.0.7204.183** (for Linux) or **138.0.7204.183/.184** (for Windows and Mac) and later.
### Workarounds
- Apply the Principle of Least Privilege (M1026) to all user accounts to reduce the impact of successful exploitation.
- Restrict the use of administrative accounts for general computing tasks like web browsing.
- Restrict execution of code within virtual environments or sandboxes (M1048).
- Restrict web content execution (e.g., block Javascript, restrict extensions) (M1021).
## Detection
- Indicators of Compromise (IOCs): Not specified in the provided text.
- Detection methods and tools: Use capabilities to detect and block conditions indicative of a software exploit occurring (M1050). Enable anti-exploitation features such as DEP, WDEG, SIP, and Gatekeeper (M1050, Safeguard 10.5).
