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

  - CVE-2017-15649: net/packet/af_packet.c in the Linux     kernel allowed local users to gain privileges via     crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind) that     leads to a use-after-free, a different vulnerability     than CVE-2017-6346 (bnc#1064388).

  - CVE-2015-9004: kernel/events/core.c in the Linux kernel     mishandled counter grouping, which allowed local users     to gain privileges via a crafted application, related to     the perf_pmu_register and perf_event_open functions     (bnc#1037306).

  - CVE-2016-10229: udp.c in the Linux kernel allowed remote     attackers to execute arbitrary code via UDP traffic that     triggers an unsafe second checksum calculation during     execution of a recv system call with the MSG_PEEK flag     (bnc#1032268).

  - CVE-2016-9604: The handling of keyrings starting with     '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have     allowed local users to manipulate privileged keyrings,     was fixed (bsc#1035576)

  - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds     Write. Due to a missing bounds check, and the fact that     parport_ptr integer is static, a 'secure boot' kernel     command line adversary (can happen due to bootloader     vulns, e.g. Google Nexus 6's CVE-2016-10277, where due     to a vulnerability the adversary has partial control     over the command line) can overflow the parport_nr array     in the following code, by appending many (>LP_NO)     'lp=none' arguments to the command line (bnc#1039456).

  - CVE-2017-1000365: The Linux Kernel imposes a size     restriction on the arguments and environmental strings     passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the     size), but did not take the argument and environment     pointers into account, which allowed attackers to bypass     this limitation. (bnc#1039354).

  - CVE-2017-1000380: sound/core/timer.c in the Linux kernel     is vulnerable to a data race in the ALSA /dev/snd/timer     driver resulting in local users being able to read     information belonging to other users, i.e.,     uninitialized memory contents may be disclosed when a     read and an ioctl happen at the same time (bnc#1044125).

  - CVE-2017-10661: Race condition in fs/timerfd.c in the     Linux kernel allowed local users to gain privileges or     cause a denial of service (list corruption or     use-after-free) via simultaneous file-descriptor     operations that leverage improper might_cancel queueing     (bnc#1053152).

  - CVE-2017-11176: The mq_notify function in the Linux     kernel did not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a     Netlink socket, it allowed attackers to cause a denial     of service (use-after-free) or possibly have unspecified     other impact (bnc#1048275).

  - CVE-2017-12153: A security flaw was discovered in the     nl80211_set_rekey_data() function in     net/wireless/nl80211.c in the Linux kernel This function     did not check whether the required attributes are     present in a Netlink request. This request can be issued     by a user with the CAP_NET_ADMIN capability and may     result in a NULL pointer dereference and system crash     (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in     arch/x86/kvm/vmx.c in the Linux kernel did not ensure     that the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allowed KVM L2 guest     OS users to obtain read and write access to the hardware     CR8 register (bnc#1058507).

  - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A     user-controlled buffer is copied into a local buffer of     constant size using strcpy without a length check which     can cause a buffer overflow. (bnc#1053148).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)     allowed reinstallation of the Group Temporal Key (GTK)     during the group key handshake, allowing an attacker     within radio range to replay frames from access points     to clients (bnc#1063667).

  - CVE-2017-14051: An integer overflow in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption and system crash) by leveraging root access     (bnc#1056588).

  - CVE-2017-14106: The tcp_disconnect function in     net/ipv4/tcp.c in the Linux kernel allowed local users     to cause a denial of service (__tcp_select_window     divide-by-zero error and system crash) by triggering a     disconnect within a certain tcp_recvmsg code path     (bnc#1056982).

  - CVE-2017-14140: The move_pages system call in     mm/migrate.c in the Linux kernel doesn't check the     effective uid of the target process, enabling a local     attacker to learn the memory layout of a setuid     executable despite ASLR (bnc#1057179).

  - CVE-2017-15265: Use-after-free vulnerability in the     Linux kernel allowed local users to have unspecified     impact via vectors related to /dev/snd/seq     (bnc#1062520).

  - CVE-2017-15274: security/keys/keyctl.c in the Linux     kernel did not consider the case of a NULL payload in     conjunction with a nonzero length value, which allowed     local users to cause a denial of service (NULL pointer     dereference and OOPS) via a crafted add_key or keyctl     system call, a different vulnerability than     CVE-2017-12192 (bnc#1045327).

  - CVE-2017-2647: The KEYS subsystem in the Linux kernel     allowed local users to gain privileges or cause a denial     of service (NULL pointer dereference and system crash)     via vectors involving a NULL value for a certain match     field, related to the keyring_search_iterator function     in keyring.c (bnc#1030593).

  - CVE-2017-6951: The keyring_search_aux function in     security/keys/keyring.c in the Linux kernel allowed     local users to cause a denial of service (NULL pointer     dereference and OOPS) via a request_key system call for     the 'dead' type (bnc#1029850).

  - CVE-2017-7482: A potential memory corruption was fixed     in decoding of krb5 principals in the kernels kerberos     handling. (bnc#1046107).

  - CVE-2017-7487: The ipxitf_ioctl function in     net/ipx/af_ipx.c in the Linux kernel mishandled     reference counts, which allowed local users to cause a     denial of service (use-after-free) or possibly have     unspecified other impact via a failed SIOCGIFADDR ioctl     call for an IPX interface (bnc#1038879).

  - CVE-2017-7518: The Linux kernel was vulnerable to an     incorrect debug exception(#DB) error. It could occur     while emulating a syscall instruction and potentially     lead to guest privilege escalation. (bsc#1045922).

  - CVE-2017-7541: The brcmf_cfg80211_mgmt_tx function in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021     1.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-2017-7542: 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-2017-7889: The mm subsystem in the Linux kernel did     not properly enforce the CONFIG_STRICT_DEVMEM protection     mechanism, which allowed local users to read or write to     kernel memory locations in the first megabyte (and     bypass slab-allocation access restrictions) via an     application that opens the /dev/mem file, related to     arch/x86/mm/init.c and drivers/char/mem.c (bnc#1034405).

  - CVE-2017-8106: The handle_invept function in     arch/x86/kvm/vmx.c in the Linux kernel 3.12 allowed     privileged KVM guest OS users to cause a denial of     service (NULL pointer dereference and host OS crash) via     a single-context INVEPT instruction with a NULL EPT     pointer (bnc#1035877).

  - 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).

  - CVE-2017-8890: The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allowed attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call (bnc#1038544).

  - CVE-2017-8924: The edge_bulk_in_callback function in     drivers/usb/serial/io_ti.c in the Linux kernel allowed     local users to obtain sensitive information (in the     dmesg ringbuffer and syslog) from uninitialized kernel     memory by using a crafted USB device (posing as an io_ti     USB serial device) to trigger an integer underflow     (bnc#1037182 bsc#1038982).

  - CVE-2017-8925: The omninet_open function in     drivers/usb/serial/omninet.c in the Linux kernel allowed     local users to cause a denial of service (tty     exhaustion) by leveraging reference count mishandling     (bnc#1037183 bsc#1038981).

  - CVE-2017-9074: The IPv6 fragmentation implementation in     the Linux kernel did not consider that the nexthdr field     may be associated with an invalid option, which allowed     local users to cause a denial of service (out-of-bounds     read and BUG) or possibly have unspecified other impact     via crafted socket and send system calls (bnc#1039882).

  - CVE-2017-9075: The sctp_v6_create_accept_sk function in     net/sctp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed local users to cause a denial     of service or possibly have unspecified other impact via     crafted system calls, a related issue to CVE-2017-8890     (bnc#1039883).

  - CVE-2017-9076: The dccp_v6_request_recv_sock function in     net/dccp/ipv6.c in the Linux kernel mishandled     inheritance, which allowed local users to cause a denial     of service or possibly have unspecified other impact via     crafted system calls, a related issue to CVE-2017-8890     (bnc#1039885).

  - CVE-2017-9077: The tcp_v6_syn_recv_sock function in     net/ipv6/tcp_ipv6.c in the Linux kernel mishandled     inheritance, which allowed local users to cause a denial     of service or possibly have unspecified other impact via     crafted system calls, a related issue to CVE-2017-8890     (bnc#1040069).

  - CVE-2017-9242: The __ip6_append_data function in     net/ipv6/ip6_output.c in the Linux kernel is too late in     checking whether an overwrite of an skb data structure     may occur, which allowed local users to cause a denial     of service (system crash) via crafted system calls     (bnc#1041431).

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