            Description

            When the Packet Socket API is used with UDP protocol sockets a crash of the firmware might occur. The problem affects usecases where a socket with type SOCK_SOCKET_DGRAM and protocol SOCK_IPPROTO_UDP is used. The problem occurs more likely under the condition of high socket traffic. It is expected that no such crash occurs.

            There is no workaround. An update of the firmware is required to solve this issue.
