Detail

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

gtp: fix a potential NULL pointer dereference

When sockfd_lookup() fails, gtp_encap_enable_socket() returns a NULL pointer, but its callers only check for error pointers thus miss the NULL pointer case.

Fix it by returning an error pointer with the error code carried from sockfd_lookup().

(I found this bug during code inspection.)
