This update for the Linux Kernel 4.4.140-94_42 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). - CVE-2018-3646: Fixed unauthorized disclosure of information residing in the L1 data cache on systems with microprocessors utilizing speculative execution and address translations (bsc#1099306).
