The AUSF component of free5GC versions up to 1.4.4 has a vulnerability where concurrent authentication requests for the same subscriber identity (SUPI) overwrite the authentication context. This causes legitimate authentication responses to fail verification, resulting in a denial of service for that subscriber. The issue arises because the authentication context is stored in a global map keyed only by SUPI without session uniqueness or concurrency control.
