"The openSUSE Leap 42.2 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed :

  - CVE-2017-1000111: Fixed a race condition in net-packet
    code that could be exploited to cause out-of-bounds
    memory access (bsc#1052365).

  - CVE-2017-1000112: Fixed a race condition in net-packet
    code that could have been exploited by unprivileged
    users to gain root access. (bsc#1052311).

  - CVE-2017-8831: The saa7164_bus_get function in
    drivers/media/pci/saa7164/saa7164-bus.c in the Linux
    kernel allowed local users to cause a denial of service
    (out-of-bounds array access) or possibly have
    unspecified other impact by changing a certain
    sequence-number value, aka a 'double fetch'
    vulnerability (bnc#1037994).

The following non-security bugs were fixed :

  - IB/hfi1: Wait for QSFP modules to initialize
    (bsc#1019151).

  - bcache: force trigger gc (bsc#1038078).

  - bcache: only recovery I/O error for writethrough mode
    (bsc#1043652).

  - block: do not allow updates through sysfs until
    registration completes (bsc#1047027).

  - ibmvnic: Check for transport event on driver resume
    (bsc#1051556, bsc#1052709).

  - ibmvnic: Initialize SCRQ's during login renegotiation
    (bsc#1052223).

  - ibmvnic: Report rx buffer return codes as netdev_dbg
    (bsc#1052794).

  - iommu/amd: Fix schedule-while-atomic BUG in
    initialization code (bsc1052533).

  - libnvdimm, pmem: fix a NULL pointer BUG in
    nd_pmem_notify (bsc#1023175).

  - libnvdimm: fix badblock range handling of ARS range
    (bsc#1023175).

  - qeth: fix L3 next-hop im xmit qeth hdr (bnc#1052773,
    LTC#157374).

  - scsi_devinfo: fixup string compare (bsc#1037404).

  - scsi_dh_alua: suppress errors from unsupported devices
    (bsc#1038792).

  - vfs: fix missing inode_get_dev sites (bsc#1052049).

  - x86/dmi: Switch dmi_remap() from ioremap() to
    ioremap_cache() (bsc#1051399)."
