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-2023-24942 is a Remote Procedure Call Runtime Denial of Service issue affecting the Remote Procedure Call component. It is rated 7.5 under CVSS 3.1 with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H and is associated with CWE-126.

An unauthenticated remote attacker can trigger the flaw over the network to produce a denial-of-service condition that impairs availability while leaving confidentiality and integrity unaffected.

The listed references direct practitioners to the Microsoft Security Response Center advisory for patch availability and mitigation guidance. The EPSS score has remained flat at its recorded peak of 0.1372.
