What is CVE-2023-37023?

Open5GS MME, specifically in versions up to 2.6.4, is affected by a vulnerability allowing remote attackers to crash the service by exploiting a reachable assertion in the Uplink NAS Transport packet handler. This vulnerability arises when an attacker sends packets that lack the required MME_UE_S1AP_ID field, leading to a denial-of-service condition as the system fails to process these malformed packets correctly.
