Deeper analysis

CVE-2025-29313 is a vulnerability involving the use of an incorrectly resolved name or reference in the OpenDaylight Service Function Chaining (SFC) Subproject, specifically affecting SFC Sodium-SR4 and earlier versions. This flaw, classified under CWE-404, enables attackers to trigger a Denial of Service (DoS) condition. The vulnerability received a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity due to its network accessibility, low attack complexity, and lack of required privileges, with a high impact on availability but no effects on confidentiality or integrity. It was published on 2025-03-24.

Any remote attacker without authentication can exploit this vulnerability over the network with minimal effort. Successful exploitation leads to a DoS, disrupting service availability in affected OpenDaylight SFC deployments, potentially halting service function chaining operations.
