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: Multiple Vulnerabilities in Google Chrome (June 2026)
## CVE Details
- **CVE ID:** CVE-2026-13774 through CVE-2026-14136 (Multiple)
- **CVSS Score:** Not explicitly provided; rated as **High** risk by MS-ISAC.
- **CWE:** Primarily Use-After-Free (CWE-416), Heap Buffer Overflow (CWE-122), Type Confusion (CWE-843), and Integer Overflow (CWE-190).
## Affected Systems
- **Products:** Google Chrome Browser
- **Versions:**
- Chrome prior to 150.0.7871.46/.47 for Windows and macOS
- Chrome prior to 150.0.7871.46 for Linux
- **Configurations:** Systems where users operate with administrative privileges are at higher risk.
## Vulnerability Description
Multiple technical flaws exist across various Chrome components including extensions, GPU, Blink engine, Skia, and ANGLE. The most severe vulnerabilities are **Use-After-Free** and **Heap Buffer Overflow** conditions. These occur when the browser continues to use a memory pointer after it has been cleared, or fails to verify memory boundaries, allowing an attacker to inject and execute malicious code within the context of the current user.
## Exploitation
- **Status:** Not currently reported as exploited in the wild; no PoC is publicly available.
- **Complexity:** Medium (requires crafting specific web content to trigger memory corruption).
- **Attack Vector:** Network (Remote/Web-based via Drive-By Compromise).
## Impact
- **Confidentiality:** High (Attacker can view and exfiltrate data).
- **Integrity:** High (Attacker can change/delete data or install unauthorized programs).
- **Availability:** High (Attacker can crash the system or create new administrative accounts).
## Remediation
### Patches
Update Google Chrome to the following versions or higher:
- **Windows/macOS:** 150.0.7871.46/.47
- **Linux:** 150.0.7871.46
### Workarounds
- **Least Privilege:** Operate systems using non-administrative accounts to limit the scope of a potential compromise.
- **Web Filtering:** Block access to suspicious or untrusted websites to reduce the risk of drive-by downloads.
## Detection
- **Indicators of Compromise:** Unusual browser crashes, unauthorized changes to browser settings, or unexplained creation of new user accounts.
- **Detection methods and tools:**
- Vulnerability scanners (Nessus, Qualys) to identify outdated Chrome binaries.
- Endpoint Detection and Response (EDR) tools to monitor for suspicious child processes spawned by `chrome.exe`.
