update for the Linux Kernel","description":"\nThe SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes.\n\nThe following security bugs were fixed:\n\n- CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall interface\n  for bridging. This allowed a privileged user to arbitrarily write to a limited\n  range of kernel memory (bnc#1085107).\n- CVE-2017-18221: The __munlock_pagevec function allowed local users to cause a\n  denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall\n  and munlockall system calls (bnc#1084323).\n- CVE-2018-1066: Prevent NULL pointer dereference in\n  fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an attacker controlling a\n  CIFS server to kernel panic a client that has this server mounted, because an\n  empty TargetInfo field in an NTLMSSP setup negotiation response was mishandled\n  during session recovery (bnc#1083640).\n- CVE-2017-13166: Prevent elevation of privilege vulnerability in the kernel\n  v4l2 video driver (bnc#1072865).\n- CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose\n  kernel memory addresses. Successful exploitation required that a USB device was\n  attached over IP (bnc#1078674).\n- CVE-2017-15299: The KEYS subsystem mishandled use of add_key for a key that\n  already exists but is uninstantiated, which allowed local users to cause a\n  denial of service (NULL pointer dereference and system crash) or possibly have\n  unspecified other impact via a crafted system call (bnc#1063416).\n- CVE-2017-18208: The madvise_willneed function kernel allowed local users to\n  cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED\n  for a DAX mapping (bnc#1083494).\n- CVE-2018-7566: The ALSA sequencer core initializes the event pool on demand\n  by invoking snd_seq_pool_init() when the first write happens and the pool is\n  empty. A user could have reset the pool size manually via ioctl concurrently,\n  which may have lead UAF or out-of-bound access (bsc#1083483).\n- CVE-2017-18204: The ocfs2_setattr function allowed local users to cause a\n  denial of service (deadlock) via DIO requests (bnc#1083244).\n- CVE-2017-16644: The hdpvr_probe function allowed local users to cause a\n  denial of service (improper error handling and system crash) or possibly have\n  unspecified other impact via a crafted USB device (bnc#1067118).\n- CVE-2018-6927: The futex_requeue function allowed attackers to cause a denial\n  of service (integer overflow) or possibly have unspecified other impact by\n  triggering a negative wake or requeue value (bnc#1080757).\n- CVE-2017-16914: The 'stub_send_ret_submit()' function allowed attackers to\n  cause a denial of service (NULL pointer dereference) via a specially crafted\n  USB over IP packet (bnc#1078669).\n- CVE-2016-7915: The hid_input_field function allowed physically proximate\n  attackers to obtain sensitive information from kernel memory or cause a denial\n  of service (out-of-bounds read) by connecting a device (bnc#1010470).\n- CVE-2017-12190: The bio_map_user_iov and bio_unmap_user functions did\n  unbalanced refcounting when a SCSI I/O vector had small consecutive buffers\n  belonging to the same page. The bio_add_pc_page function merged them into one,\n  but the page reference was never dropped.
