   An update that solves three vulnerabilities and has one
   errata is now available.

Description:

   This update for the Linux Kernel 4.4.121-92_92 fixes several issues.

   The following security issues were fixed:

   - CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue()
     and tcp_prune_ofo_queue() for every incoming TCP packet which can lead
     to a denial of service (bsc#1102682).
   - CVE-2018-10938: Fixed an infinite loop in the cipso_v4_optptr() function
     leading to a denial-of-service via crafted network packets (bsc#1106191).
   - CVE-2018-10902: It was found that the raw midi kernel driver did not
     protect against concurrent access which lead to a double realloc (double
     free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(),
     allowing a malicious local attacker to use this for privilege escalation
     (bsc#1105323).
