Description
In the Linux kernel, the following vulnerability has been resolved:
net/sctp: fix a null dereference in sctp_disposition sctp_sf_do_5_1D_ce()
If new_asoc->peer.adaptation_ind=0 and sctp_ulpevent_make_authkey=0
and sctp_ulpevent_make_authkey() returns 0, then the variable
ai_ev remains zero and the zero will be dereferenced
in the sctp_ulpevent_free() function.
