CVE-2025-36904

Comprehensive Technical Analysis of CVE-2025-36904

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-36904 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is of critical severity. This high score is likely due to the potential for significant impact, including elevation of privilege, which can lead to unauthorized access to sensitive information or system control.

Severity Evaluation:

• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: High

The elevation of privilege can allow an attacker to gain higher-level permissions, potentially leading to full system compromise. This makes the vulnerability extremely dangerous, especially in environments where sensitive data is handled.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Local Exploitation: An attacker with physical access to the device or with the ability to execute code locally could exploit this vulnerability.
• Remote Exploitation: If the WLAN functionality can be manipulated remotely, an attacker could potentially exploit this vulnerability over the network.

Exploitation Methods:

• Malicious Applications: An attacker could develop a malicious application that, when installed, exploits the vulnerability to gain elevated privileges.
• Network-Based Attacks: An attacker could send specially crafted WLAN packets to exploit the vulnerability, potentially leading to remote code execution or privilege escalation.

3. Affected Systems and Software Versions

Affected Systems:

• Google Pixel devices running Android versions before 2025-09-05.

Software Versions:

• All Android versions prior to the September 2025 security patch level on Google Pixel devices.

4. Recommended Mitigation Strategies
