  script_tag(name:"insight", value:"The openSUSE Leap 42.3 kernel was updated to 4.4.176 to receive various
  security and bugfixes.

  The following security bugs were fixed:

  - CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap
  minimum address, which made it easier for attackers to exploit kernel
  NULL pointer dereferences on non-SMAP platforms. This is related to a
  capability check for the wrong task (bnc#1128166).

  - CVE-2019-2024: A use-after-free when disconnecting a source was fixed
  which could lead to crashes. bnc#1129179).

  The following non-security bugs were fixed:

  - ax25: fix possible use-after-free (bnc#1012382).

  - block_dev: fix crash on chained bios with O_DIRECT (bsc#1090435).

  - block: do not use bio->bi_vcnt to figure out segment number
  (bsc#1128893).

  - bnxt_re: Fix couple of memory leaks that could lead to IOMMU call traces
  (bsc#1020413).

  - bpf: fix replace_map_fd_with_map_ptr's ldimm64 second imm field
  (bsc#1012382).

  - btrfs: ensure that a DUP or RAID1 block group has exactly two stripes
  (bsc#1128452).

  - ceph: avoid repeatedly adding inode to mdsc->snap_flush_list
  (bsc#1126773).

  - ch: add missing mutex_lock()/mutex_unlock() in ch_release()
  (bsc#1124235).

  - ch: fixup refcounting imbalance for SCSI devices (bsc#1124235).

  - copy_mount_string: Limit string length to PATH_MAX (bsc#1082943).

  - device property: Fix the length used in PROPERTY_ENTRY_STRING()
  (bsc#1129770).

  - Drivers: hv: vmbus: Check for ring when getting debug info (bsc#1126389).

  - drm: Fix error handling in drm_legacy_addctx (bsc#1106929)

  - drm/nouveau/bios/ramcfg: fix missing parentheses when calculating RON
  (bsc#1106929)

  - drm/nouveau/pmu: do not print reply values if exec is false (bsc#1106929)

  - drm/radeon/evergreen_cs: fix missing break in switch statement
  (bsc#1106929)

  - drm/vmwgfx: Do not double-free the mode stored in par->set_mode
  (bsc#1103429)

  - enic: add wq clean up budget (bsc#1075697, bsc#1120691. bsc#1102959).

  - enic: do not overwrite error code (bnc#1012382).

  - fbdev: chipsfb: remove set but not used variable 'size' (bsc#1106929)

  - ibmvnic: Report actual backing device speed and duplex values
  (bsc#1129923).

  - ibmvscsi: Fix empty event pool access during host removal (bsc#1119019).

  - Input: mms114 - fix license module information (bsc#1087092).

  - iommu/dmar: Fix buffer overflow during PCI bus notification
  (bsc#1129237).

  - iommu/io-pgtable-arm-v7s: Only kmemleak_ignore L2 tables (bsc#1129238).

  - iommu/vt-d: Check identity map for hot-added devices (bsc#1129239).

  - iommu/vt-d: Fix NULL pointer reference in intel_svm_bind_mm ...
