Description OSIDB Bzimport 2024-09-13 06:20:45 UTC 
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.)
