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 (August 2026)
## CVE Details
- **CVE ID:** CVE-2026-19137 through CVE-2026-19177 (Total of 41 CVEs identified)
- **CVSS Score:** Not explicitly provided, but categorized as **High/Critical** severity due to Arbitrary Code Execution (ACE) potential.
- **CWE:**
- CWE-416 (Use After Free)
- CWE-787 (Out-of-bounds Write)
- CWE-122 (Heap-based Buffer Overflow)
- CWE-190 (Integer Overflow)
- CWE-20 (Improper Input Validation)
- CWE-662 (Race Condition)
- CWE-457 (Use of Uninitialized Variable)
## Affected Systems
- **Products:** Google Chrome Browser
- **Versions:**
- Windows and Mac: Versions prior to 151.0.7922.108/.109
- Linux: Versions prior to 151.0.7922.108
- **Configurations:** Systems where users operate with high administrative privileges are at greater risk.
## Vulnerability Description
Google Chrome is affected by multiple memory safety and logic flaws. The primary technical drivers include:
- **Use After Free (UAF):** The most prevalent flaw, affecting components including WebGL, Aura, Skia, Views, GPU, HTML, and Media. These occur when the program continues to use a pointer after it has been freed, leading to memory corruption.
- **Memory Corruption:** Includes Out-of-bounds writes in the ANGLE graphics engine and V8 JavaScript engine, and Heap Buffer Overflows in CrashReporting and Base components.
- **Logic & Implementation:** Inappropriate implementations in the V8 engine and Navigation components, along with uninitialized memory use in GPU and Skia.
- **Race Conditions:** Identified in the CredentialProvider component.
## Exploitation
- **Status:** Not currently reported as exploited in the wild; no public PoC mentioned in the advisory.
- **Complexity:** Low to Medium (Exploits typically require a user to visit a malicious website).
- **Attack Vector:** Network (Remote / Drive-by Compromise).
## Impact
- **Confidentiality:** High (Attacker can view/access all data reachable by the logged-on user).
- **Integrity:** High (Attacker can change or delete data and create new accounts).
- **Availability:** High (Attacker can install programs or crash the system).
## Remediation
### Patches
Update Google Chrome to the following versions or later:
- **Windows/Mac:** 151.0.7922.108/.109
- **Linux:** 151.0.7922.108
### Workarounds
- **Principle of Least Privilege:** Run the browser as a non-privileged user to limit the scope of a successful compromise.
- **Strict Web Filtering:** Block access to untrusted or suspicious websites to reduce the risk of drive-by downloads.
## Detection
- **Indicators of Compromise:** Unusual browser crashes, unauthorized changes to browser settings, or unexpected network traffic to unknown domains.
- **Detection methods:** Automated vulnerability scanners (Qualys, Nessus, etc.) can be used to identify outdated Chrome binaries across the enterprise.
