Integer Overflow Vulnerability in Microsoft Windows Fast FAT Driver

CVE-2025-24985

What is CVE-2025-24985?

CVE-2025-24985 is a vulnerability in the Microsoft Windows Fast FAT Driver, a critical component responsible for managing file operations within the Windows operating system. This vulnerability involves an integer overflow, which permits an unauthorized attacker to execute code locally on affected systems. The implications of exploiting this vulnerability can be severe, as it may allow attackers to gain elevated privileges and manipulate system functions, leading to significant security breaches.

Technical Details

The vulnerability in question stems from a flaw within the Windows Fast FAT Driver that results in an integer overflow or wraparound condition. This technical issue can be exploited by crafting specific inputs that lead to unintended behavior, potentially allowing an attacker to execute arbitrary code. Such vulnerabilities are particularly dangerous as they can be triggered without requiring user interaction, making them easier for attackers to exploit.

Potential Impact of CVE-2025-24985

1. Unauthorized Code Execution: Attackers exploiting this vulnerability can execute arbitrary code on the victim's system, which may include installing malware, creating backdoors, or executing a broader attack strategy.

2. Privilege Escalation: Once inside the system, attackers may gain elevated privileges, allowing them to access sensitive data, manipulate files, or adjust system configurations to their advantage.

3. Widespread System Compromise: Given that the vulnerability is based in a core system driver, it could potentially affect multiple applications and services running on the Windows operating system, leading to widespread compromise across organizational networks.
