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.

- **CVSS Score**: Not explicitly provided; however, categorized as **High Risk** for government and large business entities.
- **CWE**: Multiple, including CWE-416 (Use After Free), CWE-122 (Heap-based Buffer Overflow), and CWE-843 (Type Confusion).
## Affected Systems
- **Products**: Google Chrome Desktop Browser
- **Versions**:
- Windows & Mac: Versions prior to 150.0.7871.124/.125
- Linux: Versions prior to 150.0.7871.124
- **Configurations**: Systems running Chrome with administrative privileges are at higher risk.
## Vulnerability Description
Multiple flaws exist across several Chrome components. The most critical involve **Use After Free** (Ozone, GPU, Skia) and **Type Confusion** (V8 engine). These memory corruption issues can be triggered during the processing of web content. If a user visits a specially crafted malicious website (Drive-by Compromise), the attacker can execute arbitrary code within the security context of the browser process.
## Exploitation
- **Status**: Not currently exploited in the wild; no public PoC reported at the time of advisory.
- **Complexity**: Medium to High (requires bypassing modern browser sandboxing/mitigations).
- **Attack Vector**: Network (Remote / Web-based).
## Impact
- **Confidentiality**: High (Ability to view and exfiltrate user data).
- **Integrity**: High (Ability to change/delete data or create new accounts).
- **Availability**: High (Ability to install programs or cause system instability).
## Remediation
### Patches
Update Google Chrome to the following versions or higher:
- **Windows/Mac**: 150.0.7871.124/.125
- **Linux**: 150.0.7871.124
### Workarounds
- **Principle of Least Privilege**: Run the browser as a non-privileged user to limit the scope of a potential compromise.
- **Isolate Browsing**: Use virtualized environments for accessing untrusted external sites.
## Detection
- **Indicators of Compromise**: Monitor for unusual child processes spawning from `chrome.exe` (e.g., `cmd.exe`, `powershell.exe`).
- **Detection Methods**: Use automated vulnerability scanners to identify out-of-date browser binaries. Ensure Endpoint Detection and Response (EDR) tools are monitoring for heap spray patterns or memory corruption attempts.
