Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability CVE-2024-38150 is an elevation of privilege flaw in the Windows DWM Core Library, carrying a CVSS 3.1 score of 7.8 and linked to CWE-416. It affects the Desktop Window Manager component responsible for compositing and rendering on supported Windows systems.

A local attacker with low privileges can exploit the issue without user interaction to obtain full control over confidentiality, integrity, and availability on the target system, resulting in privilege escalation from a standard user context to higher rights.

Microsoft publishes mitigation details and patch availability for this vulnerability through its Security Response Center at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-38150. The associated EPSS score has remained low, with a current value of 0.0681 and a peak of 0.0745.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover use-after-free bugs through dynamic analysis or fuzzing.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can require memory-safe constructs or languages that structurally avoid introducing use-after-free.

SC-39 Process Isolation partial match

Process isolation confines the blast radius of use-after-free memory corruption to a single execution domain.

SI-16 Memory Protection partial match

Memory protection controls limit exploitation impact by blocking unauthorized code execution from dangling pointers.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly incorporate memory-safety tooling and reviews that prevent most use-after-free defects.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover use-after-free issues via scanning or analysis but do not prevent their introduction.

PR.PS-02 partial match
prevents

Routine patching removes known use-after-free instances after they have been introduced in released software.
