The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.38 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x     provides an incomplete set of requirements for setattr     operations that underspecifies removing extended     privilege attributes, which allowed local users to cause     a denial of service (capability stripping) via a failed     invocation of a system call, as demonstrated by using     chown to remove a capability from the ping or Wireshark     dumpcap program (bnc#914939).

  - CVE-2015-8964: The tty_set_termios_ldisc function in     drivers/tty/tty_ldisc.c in the Linux kernel allowed     local users to obtain sensitive information from kernel     memory by reading a tty data structure (bnc#1010507).

  - CVE-2016-7039: The IP stack in the Linux kernel allowed     remote attackers to cause a denial of service (stack     consumption and panic) or possibly have unspecified     other impact by triggering use of the GRO path for large     crafted packets, as demonstrated by packets that contain     only VLAN headers, a related issue to CVE-2016-8666     (bnc#1001486).

  - CVE-2016-7042: The proc_keys_show function in     security/keys/proc.c in the Linux kernel through 4.8.2,     when the GNU Compiler Collection (gcc) stack protector     is enabled, uses an incorrect buffer size for certain     timeout data, which allowed local users to cause a     denial of service (stack memory corruption and panic) by     reading the /proc/keys file (bnc#1004517).

  - CVE-2016-7425: The arcmsr_iop_message_xfer function in     drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did     not restrict a certain length field, which allowed local     users to gain privileges or cause a denial of service     (heap-based buffer overflow) via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).

  - CVE-2016-7913: The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     allowed local users to gain privileges or cause a denial     of service (use-after-free) via vectors involving     omission of the firmware name from a certain data     structure (bnc#1010478).

  - CVE-2016-7917: The nfnetlink_rcv_batch function in     net/netfilter/nfnetlink.c in the Linux kernel did not     check whether a batch message's length field is large     enough, which allowed local users to obtain sensitive     information from kernel memory or cause a denial of     service (infinite loop or out-of-bounds read) by     leveraging the CAP_NET_ADMIN capability (bnc#1010444).

  - CVE-2016-8645: The TCP stack in the Linux kernel     mishandled skb truncation, which allowed local users to     cause a denial of service (system crash) via a crafted     application that made sendto system calls, related to     net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c     (bnc#1009969).

  - CVE-2016-8666: The IP stack in the Linux kernel allowed     remote attackers to cause a denial of service (stack     consumption and panic) or possibly have unspecified     other impact by triggering use of the GRO path for     packets with tunnel stacking, as demonstrated by     interleaved IPv4 headers and GRE headers, a related     issue to CVE-2016-7039 (bnc#1003964).

  - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux     kernel allowed local users to bypass integer overflow     checks, and cause a denial of service (memory     corruption) or have unspecified other impact, by     leveraging access to a vfio PCI device file for a     VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine     confusion bug (bnc#1007197).

  - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the     Linux kernel misuses the kzalloc function, which allowed     local users to cause a denial of service (integer     overflow) or have unspecified other impact by leveraging     access to a vfio PCI device file (bnc#1007197).

  - CVE-2016-9793: A bug in SO_{SND|RCV}BUFFORCE     setsockopt() implementation was fixed, which allowed     CAP_NET_ADMIN users to cause memory corruption.
    (bsc#1013531).

  - CVE-2016-9919: The icmp6_send function in     net/ipv6/icmp.c in the Linux kernel omits a certain     check of the dst data structure, which allowed remote     attackers to cause a denial of service (panic) via a     fragmented IPv6 packet (bnc#1014701).

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