1) Asymmetric Resource Consumption (Amplification) (CVE-ID: CVE-2025-24356)

CWE-ID: CWE-405 - Asymmetric Resource Consumption (Amplification)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to an error when handling UDP packets in fast reconnect feature. A remote non-authenticated attacker can send small UDP packets (even a 1-byte packet is enough) to the application and force it to initiate connections to third-party systems using much larger packets.
