       An update that solves 7 vulnerabilities and has three fixes
       is now available.
    
    Description:
    
    
    
       The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
       security and bugfixes.
    
    
       The following security bugs were fixed:
    
       - CVE-2018-5390 aka "SegmentSmack": A remote attacker even with relatively
         low bandwidth could have caused lots of CPU usage by triggering the
         worst case scenario during IP and/or TCP fragment reassembly
         (bsc#1102340)
       - CVE-2018-7191: In the tun subsystem in the Linux kernel,
         dev_get_valid_name was not called before register_netdevice. This
         allowed local users to cause a denial of service (NULL pointer
         dereference and panic) via an ioctl(TUNSETIFF) call with a dev name
         containing a / character. (bnc#1135603)
       - CVE-2018-20836: A race condition in smp_task_timedout() and
         smp_task_done() in drivers/scsi/libsas/sas_expander.c, could have lead
         to a use-after-free. (bnc#1134395)
       - CVE-2019-12614: An unchecked kstrdup might have allowed an attacker to
         cause denial of service (a NULL pointer dereference and system crash).
         (bnc#1137194)
       - CVE-2019-12818: The nfc_llcp_build_tlv function in
         net/nfc/llcp_commands.c may have returned NULL. If the caller did not
         check for this, it would trigger a NULL pointer dereference. This would
         cause denial of service. (bnc#1138293)
       - CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main()
         allowed local users to cause a denial of service or possibly have
         unspecified other impact by changing the value of ioc_number between two
         kernel reads of that value, aka a "double fetch" vulnerability.
         (bsc#1136922)
       - CVE-2019-11487: An attacker could have triggered use-after-free via page
         reference count overflow on slow filesystems with at least of 140 GiB of
         RAM available. (bnc#1133190)
    
       The following non-security bugs were fixed:
    
       - fuse: Don't access pipe->buffers without pipe_lock() (Prerequisity for
         CVE-2019-11487, bsc#1133190).
       - fuse: call pipe_buf_release() under pipe lock (Prerequisity for
         CVE-2019-11487, bsc#1133190).
       - mm: /proc/pid/maps: Check permissions when opening proc pid maps
         (bsc#1130159).
       - pipe: add pipe_buf_get() helper (Prerequisity for CVE-2019-11487,
         bsc#1133190).
       - tcp: refine memory limit test in tcp_fragment() after CVE-2019-11478 fix
         (bsc#1139751).
       - x86/bugs: do not default to IBRS even on SKL (bsc#1112824).
