The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1087: And an unprivileged KVM guest user could     use this flaw to potentially escalate their privileges     inside a guest. (bsc#1087088)

  - CVE-2018-8897: An unprivileged system user could use     incorrect set up interrupt stacks to crash the Linux     kernel resulting in DoS issue. (bsc#1087088)

  - CVE-2018-10124: The kill_something_info function in     kernel/signal.c might allow local users to cause a     denial of service via an INT_MIN argument (bnc#1089752).

  - CVE-2018-10087: The kernel_wait4 function in     kernel/exit.c might allow local users to cause a denial     of service by triggering an attempted use of the
    -INT_MIN value (bnc#1089608).

  - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events     function in drivers/scsi/libsas/sas_expander.c allowed     local users to cause a denial of service (memory     consumption) via many read accesses to files in the     /sys/class/sas_phy directory, as demonstrated by the     /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file     (bnc#1084536 1087209).

  - CVE-2018-7566: A Buffer Overflow via an     SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to     /dev/snd/seq by a local user was fixed (bnc#1083483).

  - CVE-2017-0861: Use-after-free vulnerability in the     snd_pcm_info function in the ALSA subsystem allowed     attackers to gain privileges via unspecified vectors     (bnc#1088260).

  - CVE-2018-8822: Incorrect buffer length handling in the     ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c     could be exploited by malicious NCPFS servers to crash     the kernel or execute code (bnc#1086162).

  - CVE-2017-13166: An elevation of privilege vulnerability     in the kernel v4l2 video driver. (bnc#1072865).

  - CVE-2017-18203: The dm_get_from_kobject function in     drivers/md/dm.c allow local users to cause a denial of     service (BUG) by leveraging a race condition with
    __dm_destroy during creation and removal of DM devices     (bnc#1083242).

  - CVE-2017-16911: The vhci_hcd driver allowed allows local     attackers to disclose kernel memory addresses.
    Successful exploitation requires that a USB device is     attached over IP (bnc#1078674).

  - CVE-2017-18208: The madvise_willneed function in     mm/madvise.c allowed local users to cause a denial of     service (infinite loop) by triggering use of     MADVISE_WILLNEED for a DAX mapping (bnc#1083494).

  - CVE-2017-16644: The hdpvr_probe function in     drivers/media/usb/hdpvr/hdpvr-core.c allowed local users     to cause a denial of service (improper error handling     and system crash) or possibly have unspecified other     impact via a crafted USB device (bnc#1067118).

  - CVE-2018-6927: The futex_requeue function in     kernel/futex.c might allow attackers to cause a denial     of service (integer overflow) or possibly have     unspecified other impact by triggering a negative wake     or requeue value (bnc#1080757).

  - CVE-2017-16914: The 'stub_send_ret_submit()' function     (drivers/usb/usbip/stub_tx.c) allowed attackers to cause     a denial of service (NULL pointer dereference) via a     specially crafted USB over IP packet (bnc#1078669).

  - CVE-2016-7915: The hid_input_field function in     drivers/hid/hid-core.c allowed physically proximate     attackers to obtain sensitive information from kernel     memory or cause a denial of service (out-of-bounds read)     by connecting a device, as demonstrated by a Logitech DJ     receiver (bnc#1010470).

  - CVE-2015-5156: The virtnet_probe function in     drivers/net/virtio_net.c attempted to support a FRAGLIST     feature without proper memory allocation, which allowed     guest OS users to cause a denial of service (buffer     overflow and memory corruption) via a crafted sequence     of fragmented packets (bnc#940776).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user     functions in block/bio.c did unbalanced refcounting when     a SCSI I/O vector has small consecutive buffers     belonging to the same page. The bio_add_pc_page function     merges them into one, but the page reference is never     dropped. This causes a memory leak and possible system     lockup (exploitable against the host OS by a guest OS     user, if a SCSI disk is passed through to a virtual     machine) due to an out-of-memory condition     (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function     (drivers/usb/usbip/stub_rx.c) allowed attackers to cause     a denial of service (out-of-bounds read) via a specially     crafted USB over IP packet (bnc#1078673).

  - CVE-2017-16913: The 'stub_recv_cmd_submit()' function     (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT     packets allowed attackers to cause a denial of service     (arbitrary memory allocation) via a specially crafted     USB over IP packet (bnc#1078672).

The update package also includes non-security fixes. See advisory for details.
