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 (Arbitrary Code Execution)
## CVE Details
- **CVE ID:** CVE-2026-106382, CVE-2026-106197, CVE-2026-106358, CVE-2026-106347, CVE-2026-106240, and others (Totaling over 80+ unique identifiers).
- **CVSS Score:** Not explicitly provided in the advisory; however, the severity is classified as **High** due to the potential for Arbitrary Code Execution (ACE).
- **CWE:** Multiple, including CWE-416 (Use After Free), CWE-843 (Type Confusion), CWE-362 (Race Condition), and CWE-190 (Integer Overflow).
## Affected Systems
- **Products:** Google Chrome Browser
- **Versions:**
- Chrome prior to 155.0.8059.39/.40 for Windows and Mac
- Chrome prior to 155.0.8059.39 for Linux
- **Configurations:** Systems where users operate with high-level administrative privileges are at the greatest risk.
## Vulnerability Description
Multiple security flaws exist within various Google Chrome components, including the V8 engine, ANGLE graphics layer, Skia, and the core browser navigation system. The most critical flaws involve **Use-After-Free** conditions and **Type Confusion** in V8 and ANGLE. These vulnerabilities occur when the application continues to use a pointer after it has been freed or incorrectly interprets data structures, leading to memory corruption.
## Exploitation
- **Status:** Not exploited in the wild (as of Oct 7, 2026).
- **Complexity:** Medium
- **Attack Vector:** Network (Remote / Drive-By Compromise). An attacker could exploit these by enticing a user to visit a specially crafted malicious website.
## Impact
- **Confidentiality:** High (Attacker can view/extract data).
- **Integrity:** High (Attacker can change or delete data and create new accounts).
- **Availability:** High (Attacker can install malicious programs or cause system crashes).
## Remediation
### Patches
Apply the following updates immediately:
- **Windows and Mac:** Update to Google Chrome version 155.0.8059.39/.40 or later.
- **Linux:** Update to Google Chrome version 155.0.8059.39 or later.
### Workarounds
- Run all software as a non-privileged user (Least Privilege) to diminish the impact of successful code execution.
- Remind users not to visit untrusted websites or follow links from unknown sources.
## Detection
- **Indicators of Compromise:** Unusual browser crashes, unauthorized changes to browser settings, or unexplained creation of new user accounts.
- **Detection methods and tools:**
- Use Vulnerability Scanners to identify outdated Chrome installations.
- Monitor network traffic for connections to known malicious domains associated with drive-by downloads.
