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

  - CVE-2018-1068: Fixed flaw in the implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory (bnc#1085107).

  - CVE-2017-18221: The __munlock_pagevec function allowed     local users to cause a denial of service (NR_MLOCK     accounting corruption) via crafted use of mlockall and     munlockall system calls (bnc#1084323).

  - CVE-2018-1066: Prevent NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response was mishandled during session recovery     (bnc#1083640).

  - CVE-2017-13166: Prevent elevation of privilege     vulnerability in the kernel v4l2 video driver     (bnc#1072865).

  - CVE-2017-16911: The vhci_hcd driver allowed local     attackers to disclose kernel memory addresses.
    Successful exploitation required that a USB device was     attached over IP (bnc#1078674).

  - CVE-2017-15299: The KEYS subsystem mishandled use of     add_key for a key that already exists but is     uninstantiated, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted system call (bnc#1063416).

  - CVE-2017-18208: The madvise_willneed function kernel     allowed local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping (bnc#1083494).

  - CVE-2018-7566: The ALSA sequencer core initializes the     event pool on demand by invoking snd_seq_pool_init()     when the first write happens and the pool is empty. A     user could have reset the pool size manually via ioctl     concurrently, which may have lead UAF or out-of-bound     access (bsc#1083483).

  - CVE-2017-18204: The ocfs2_setattr function allowed local     users to cause a denial of service (deadlock) via DIO     requests (bnc#1083244).

  - CVE-2017-16644: The hdpvr_probe function allowed local     users to cause a denial of service (improper error     handling and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067118).

  - CVE-2018-6927: The futex_requeue function allowed     attackers to cause a denial of service (integer     overflow) or possibly have unspecified other impact by     triggering a negative wake or requeue value     (bnc#1080757).

  - CVE-2017-16914: The 'stub_send_ret_submit()' function     allowed attackers to cause a denial of service (NULL     pointer dereference) via a specially crafted USB over IP     packet (bnc#1078669).

  - CVE-2016-7915: The hid_input_field function allowed     physically proximate attackers to obtain sensitive     information from kernel memory or cause a denial of     service (out-of-bounds read) by connecting a device     (bnc#1010470).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user     functions did unbalanced refcounting when a SCSI I/O     vector had small consecutive buffers belonging to the     same page. The bio_add_pc_page function merged them into     one, but the page reference was never dropped. This     caused a memory leak and possible system lockup     (exploitable against the host OS by a guest OS user, if     a SCSI disk is passed through to a virtual machine) due     to an out-of-memory condition (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function allowed     attackers to cause a denial of service (out-of-bounds     read) via a specially crafted USB over IP packet     (bnc#1078673).

  - CVE-2017-16913: The 'stub_recv_cmd_submit()' function     when handling CMD_SUBMIT packets allowed attackers to     cause a denial of service (arbitrary memory allocation)     via a specially crafted USB over IP packet     (bnc#1078672).

  - CVE-2018-5332: The rds_message_alloc_sgs() function did     not validate a value that is used during DMA page     allocation, leading to a heap-based out-of-bounds write     (related to the rds_rdma_extra_size function in     net/rds/rdma.c) (bnc#1075621).

  - CVE-2018-5333: The rds_cmsg_atomic function in     net/rds/rdma.c mishandled cases where page pinning fails     or an invalid address is supplied, leading to an     rds_atomic_free_op NULL pointer dereference     (bnc#1075617).

  - CVE-2017-18017: The tcpmss_mangle_packet function     allowed remote attackers to cause a denial of service     (use-after-free and memory corruption) or possibly have     unspecified other impact by leveraging the presence of     xt_TCPMSS in an iptables action (bnc#1074488).
