The issue represents an input validation weakness (CWE\u201120) that can be exploited by an attacker who can craft a network packet matching the problematic byte sequence, resulting in an immediate loss of service for users depending on the AMF. The crash leads to a denial of service, potentially disrupting the handover and control functions within a 5G core network, but does not provide direct remote code execution or data exfiltration.", "risk_and_exploitability": "The CVSS score of 7.5 highlights a high severity, while the EPSS score of less than 1% indicates a low overall exploit probability. The vulnerability is not currently in the CISA KEV catalog, but the existence of a dedicated merge request suggests that it is being actively addressed. Attackers would need to send crafted NR protocol messages to the AMF; the crash only occurs with particular inputs, so an attacker might need to perform reconnaissance or trial-and-error to identify the exact payload. The risk to organizations running this software is moderate to high, largely contingent on exposure to externally reachable 5G traffic."}}}}, "created": "2026-03-30T20:56:18.687974+00:00", "updated": "2026-04-07T08:08:43.308275+00:00", "vendors": ["eurecom", "eurecom$PRODUCT$oai_cn5g_amf"]}
