   An update that solves 5 vulnerabilities and has 29 fixes is
   now available.

Description:



   The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.143 to receive
   various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-5390 aka "SegmentSmack": 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 can lead to a
     denial of service (bnc#1102340).
   - CVE-2018-14734: drivers/infiniband/core/ucma.c in the Linux kernel
     allowed ucma_leave_multicast to access a certain data structure after a
     cleanup step in ucma_process_join, which allowed attackers to cause a
     denial of service (use-after-free) (bnc#1103119).
   - CVE-2017-18344: The timer_create syscall implementation in
     kernel/time/posix-timers.c didn't properly validate the
     sigevent->sigev_notify field, which lead to out-of-bounds access in the
     show_timer function (called when /proc/$PID/timers is read). This
     allowed userspace applications to read arbitrary kernel memory (on a
     kernel built with CONFIG_POSIX_TIMERS and CONFIG_CHECKPOINT_RESTORE)
     (bnc#1102851 bnc#1103580).
   - CVE-2018-3620: Local attackers on baremetal systems could use
     speculative code patterns on hyperthreaded processors to read data
     present in the L1 Datacache used by other hyperthreads on the same CPU
     core, potentially leaking sensitive data. (bnc#1087081).
   - CVE-2018-3646: Local attackers in virtualized guest systems could use
     speculative code patterns on hyperthreaded processors to read data
     present in the L1 Datacache used by other hyperthreads on the same CPU
     core, potentially leaking sensitive data, even from other virtual
     machines or the host system. (bnc#1089343).

   The following non-security bugs were fixed:

   - Add support for 5,25,50, and 100G to 802.3ad bonding driver (bsc#1096978)
   - ahci: Disable LPM on Lenovo 50 series laptops with a too old BIOS

     two stopper threads") Preemption is already disabled inside
     cpu_stop_queue_two_works() in SLE12-SP3 because it does not have commit
     6a19005157c4 ("stop_machine: Do not disable preemption in
     stop_two_cpus()")
