In the Linux kernel, the following vulnerability has been resolved:
gtp: fix a potential NULL pointer dereference
When sockfdlookup() fails, gtpencapenablesocket() 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.)
