CVE-2024-49121 is a high-severity NULL Pointer Dereference (CWE-476) vulnerability in Microsoft Windows 10 1507. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked in the top 18% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-49121 is a denial-of-service vulnerability in the Windows Lightweight Directory Access Protocol (LDAP) component. It carries a CVSS 3.1 base score of 7.5 and is associated with CWE-476. The flaw permits remote, unauthenticated attackers to trigger a crash or resource exhaustion in affected Windows systems that expose LDAP services.
An attacker with network reachability can send specially crafted LDAP requests that require no credentials or user interaction, resulting in high impact to availability while leaving confidentiality and integrity unaffected. The attack vector is rated as network-accessible with low complexity.
Microsoft's advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-49121 supplies patch information and mitigation guidance for supported Windows versions.
The associated EPSS score rose to a peak of 0.2378 after disclosure before settling at the current value of 0.1662, indicating measurable post-publication exploitation interest.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including static analysis) directly finds null-dereference bugs before deployment.
Documented development standards and tools can enforce null-safety rules and safe pointer usage.
Engineering principles can mandate defensive coding such as explicit null checks before dereference.
