   An update that solves 7 vulnerabilities and has four fixes
   is now available.

Description:


   The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2019-3459: A heap address information leak while using
     L2CAP_GET_CONF_OPT was discovered in the Linux kernel(bnc#1120758).
   - CVE-2019-3460: A heap data infoleak in multiple locations including
     L2CAP_PARSE_CONF_RSP was found in the Linux kernel before (bnc#1120758).
   - CVE-2019-3896: A double-free could happen in idr_remove_all() in
     lib/idr.c in the Linux kernel. An unprivileged local attacker could use
     this flaw for a privilege escalation or for a system crash and a denial
     of service (DoS) (bnc#1138943).
   - CVE-2018-5390: The Linux kernel could be forced to make very expensive
     calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every
     incoming packet which could lead to a denial of service (bnc#1102340).
   - CVE-2018-20836: An issue was discovered in the Linux kernel There was a
     race condition in smp_task_timedout() and smp_task_done() in
     drivers/scsi/libsas/sas_expander.c, leading to a use-after-free
     (bnc#1134395).
   - CVE-2019-12614: An issue was discovered in dlpar_parse_cc_property in
     arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel There was an
     unchecked kstrdup of prop-name, which might allow an attacker to cause a
     denial of service (NULL pointer dereference and system crash)
     (bnc#1137194).
   - CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
     possibly escalate privileges was found in the mwifiex kernel module
     while connecting to a malicious wireless network (bnc#1136424 1136446).

   The following non-security bugs were fixed:

   - KEYS: do not let add_key() update an uninstantiated key (bnc#1063416).
   - fnic: Fix to cleanup aborted IO to avoid device being offlined by
     mid-layer (bsc#1134835).
   - signal: give SEND_SIG_FORCED more power to beat SIGNAL_UNKILLABLE
     (bsc#1135650).
   - signal: oom_kill_task: use SEND_SIG_FORCED instead of force_sig()
     (bsc#1135650).
   - tcp: a regression in the previous fix for the TCP SACK issue was fixed
     (bnc#1139751)
