Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Windows CryptoAPI contains a denial-of-service vulnerability tracked as CVE-2023-24938 and assigned CWE-476. The flaw resides in the Windows cryptographic API component and carries a CVSS 3.1 score of 6.5, reflecting network attack vector, low complexity, and low required privileges with high impact solely on availability.
An authenticated attacker with low privileges can send specially crafted network requests to trigger the flaw, resulting in a NULL pointer dereference that crashes the affected service and produces a denial-of-service condition without affecting confidentiality or integrity.
Microsoft has published remediation guidance in its Security Response Center advisory at the listed MSRC URL, which security practitioners should consult for patch availability and deployment instructions.
EPSS scores have remained low and stable near 0.05 with no material increase after disclosure.
