CVE-2025-22408

Comprehensive Technical Analysis of CVE-2025-22408

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-22408 CVSS Score: 9.8

The vulnerability in question, CVE-2025-22408, is a use-after-free flaw in the rfc_check_send_cmd function within rfc_utils.cc. This type of vulnerability occurs when a program continues to use a pointer after it has been freed, potentially leading to arbitrary code execution. The CVSS score of 9.8 indicates a critical severity, reflecting the high risk associated with this vulnerability.

Severity Evaluation:

• Exploitability: The vulnerability can be exploited remotely without requiring any user interaction, making it highly exploitable.
• Impact: Successful exploitation can result in remote code execution, allowing attackers to execute arbitrary code on the affected system.
• Privileges Required: No additional execution privileges are needed, meaning that even low-privileged attackers can exploit this vulnerability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can send specially crafted packets to the vulnerable system, triggering the use-after-free condition.
• Network-Based Attacks: Given the nature of the vulnerability, it is likely exploitable over the network, making it a prime target for remote attackers.

Exploitation Methods:

• Memory Corruption: The attacker can manipulate the freed memory to inject malicious code or alter the control flow of the program.
• Code Execution: By carefully crafting the input, the attacker can achieve arbitrary code execution, potentially leading to full system compromise.

3. Affected Systems and Software Versions

Affected Systems:

• Android Devices: The vulnerability specifically affects Android devices, particularly those running the Bluetooth module.
