The vulnerability exists because the affected software improperly manages memory resources for TCP connections to a targeted device. An attacker could exploit this vulnerability by establishing a high number of TCP connections to the data interface of an affected device via IPv4 or IPv6. A successful exploit could allow the attacker to exhaust system memory, which could cause the system to stop processing new connections and result in a DoS condition. System recovery may require manual intervention.

La vulnerabilidad existe debido a que el software afectado gestiona de forma incorrecta los recursos de memoria para las conexiones TCP en un dispositivo objetivo.
