  "title": "net/af_iucv: fix NULL deref in afiucv_hs_callback_syn()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net/af_iucv: fix NULL deref in afiucv_hs_callback_syn()  afiucv_hs_callback_syn() allocates the child socket with GFP_ATOMIC. If the allocation fails, nsk is NULL.  The connection-refused path is entered when the listen state check fails, the accept backlog is full, or nsk is NULL. The code unconditionally calls iucv_sock_kill(nsk) in that path.  iucv_sock_kill() does not accept a NULL socket pointer and immediately dereferences sk via sock_flag(sk, SOCK_ZAPPED). When nsk is NULL, calling iucv_sock_kill(nsk) results in a NULL pointer dereference.  Only call iucv_sock_kill() when a child socket was successfully allocated.",
