Security update for the Linux Kernel (important)

The openSUSE Leap 42.2 kernel was updated to 4.4.79 to receive various
security and bugfixes.

The following security bugs were fixed:

• CVE-2017-7542: The ip6_find_1stfragopt function in
  net/ipv6/output_core.c in the Linux kernel allowed local users to cause
  a denial of service (integer overflow and infinite loop) by leveraging
  the ability to open a raw socket (bnc#1049882).
• CVE-2017-11473: Buffer overflow in the mp_override_legacy_irq() function
  in arch/x86/kernel/acpi/boot.c in the Linux kernel allowed local users
  to gain privileges via a crafted ACPI table (bnc#1049603).
• CVE-2017-7533: A bug in inotify code allowed local users to escalate
  privilege (bnc#1049483).
• CVE-2017-7541: The brcmf_cfg80211_mgmt_tx function in
  drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux
  kernel allowed local users to cause a denial of service (buffer overflow
  and system crash) or possibly gain privileges via a crafted
  NL80211_CMD_FRAME Netlink packet (bnc#1049645).
• CVE-2017-10810: Memory leak in the virtio_gpu_object_create function in
  drivers/gpu/drm/virtio/virtgpu_object.c in the Linux kernel allowed
  attackers to cause a denial of service (memory consumption) by
  triggering object-initialization failures (bnc#1047277).
