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-2023-24940 is a denial-of-service vulnerability in the Windows Pragmatic General Multicast (PGM) component. It carries a CVSS 3.1 base score of 7.5 and is associated with CWE-476 (NULL Pointer Dereference). The flaw permits an unauthenticated network attacker to trigger a crash or resource exhaustion in affected Windows systems.
An attacker can send specially crafted PGM traffic over the network without authentication 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 Security Response Center advisories at the referenced URLs describe available updates and mitigation guidance for the vulnerability. The associated EPSS score has remained stable at 0.1619 with no material increase observed after disclosure.
