Description The issue is caused by insufficient validation of certain fields in SCTP messages, leading to an integer overflow vulnerability. A remote unauthenticated attacker could send a crafted SCTP message to the device, potentially causing a system reboot. The vulnerability can be exploited by sending a specially crafted SCTP message, allowing a remote attacker to reboot the system.
