Summary
In the Linux kernel, the following vulnerability has been resolved: tipc: Check the bearer type before calling tipc_udp_nl_bearer_add() syzbot reported the following general protection fault [1]: general protection fault, probably for non-canonical address 0xdffffc0000000010: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000080-0x0000000000000087] ... RIP: 0010:tipc_udp_is_known_peer+0x9c/0x250 net/tipc/udp_media.c:291 ...

This patch fixes the issue by checking the bearer type before calling tipc_udp_nl_bearer_add() in tipc_nl_bearer_add().
