Summary

In the Linux kernel, the following vulnerability has been resolved:

tipc: Return non-zero value from tipc_udp_addr2str() on error

tipc_udp_addr2str() should return non-zero value if the UDP media address is invalid. Otherwise, a buffer overflow access can occur in tipc_media_addr_printf(). Fix this by returning 1 on an invalid UDP media address.
