CVE-2024-26663

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] ...

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

Este parche soluciona el problema al verificar el tipo de portador antes de llamar a tipc_udp_nl_bearer_add() en tipc_nl_bearer_add().
