Description
The issue allows remote attackers to cause a denial of service (device reload) by sending malformed IKEv2 packets over IPv4 or IPv6. This is due to how an affected device processes certain malformed IKEv2 packets. An attacker could exploit this by sending malformed IKEv2 packets to an affected device to be processed, potentially causing a reload of the device or excessive consumption of resources leading to a denial of service condition.
