An attacker could exploit this vulnerability by crafting a malicious packet with specific characteristics and sending it to a targeted device. A successful exploit could allow the attacker to bypass the L3 and L4 traffic filters and inject an arbitrary packet into the network. There are no workarounds that address this vulnerability.
