CVE-2023-37006 is a denial-of-service vulnerability affecting Open5GS MME versions up to 2.6.4. An attacker can remotely trigger an assertion failure by sending a malformed ASN.1 Handover Request Ack message over the S1AP interface, specifically by omitting the required MME_UE_S1AP_ID field. This repeatedly crashes the MME, leading to a denial of service. Rated as MEDIUM severity (CVSS 5.3), the attack requires local network access and low privileges. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
