Technical Details for CVE-2025-24983

Vulnerability Analysis

CVE-2025-24983 is a use after free vulnerability within the Windows Win32 Kernel Subsystem. The defect arises from improper handling and freeing of memory, which can be exploited to execute arbitrary code with elevated privileges.

Root Cause

A flawed memory management logic within the subsystem that fails to adequately track memory references, leading to memory being freed prematurely while still being referenced, creating potential for exploitation.

Attack Vector

The attack is executed locally, requiring initial access but allowing the attacker to leverage the vulnerability for privilege escalation.

// Example exploitation code (sanitized)
#include <windows.h>

void exploit() {
    // Simulated vulnerable function call
    VulnerableFunction();

    // Arbitrary code execution
    ExecuteElevatedCommand();
}

Detection Methods for CVE-2025-24983

Indicators of Compromise

Unusual process behavior
Unexpected privilege escalation
Access violations in kernel logs

Detection Strategies

Employ SentinelOne Singularity XDR to detect anomalies at the endpoint level, specifically monitoring for unusual process behavior and memory manipulations consistent with use-after-free exploits.

Monitoring Recommendations

Regularly audit system and application logs for signs of access violations or anomaly detections related to kernel operations using advanced threat detection solutions.

How to Mitigate CVE-2025-24983

Immediate Actions Required

Deploy Microsoft’s security patch immediately.
Restrict access to sensitive systems
Monitor logs for unusual activities

Patch Information

Patches are available through the Microsoft Security Response Center. Ensure all affected systems are updated to mitigate this vulnerability.

Workarounds

While waiting for patches to be applied, consider restricting access to vulnerable systems and employing endpoint detection solutions capable of recognizing exploit attempts.
