  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to
 potentially escalate their privileges inside a guest. (bsc#1087088)
- CVE-2018-8897: An unprivileged system user could use incorrect set up
 interrupt stacks to crash the Linux kernel resulting in DoS issue.
 (bsc#1087088)
- CVE-2018-8781: The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c
 had an integer-overflow vulnerability allowing local users with access
 to the udldrmfb driver to obtain full read and write permissions on
 kernel physical pages, resulting in a code execution in kernel space
 (bnc#1090643).
- CVE-2018-10124: The kill_something_info function in kernel/signal.c
 might allow local users to cause a denial of service via an INT_MIN
 argument (bnc#1089752).
- CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might allow
 local users to cause a denial of service by triggering an attempted use
 of the -INT_MIN value (bnc#1089608).
- CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in
 drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial
 of service (memory consumption) via many read accesses to files in the
 /sys/class/sas_phy directory, as demonstrated by the
 /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536
 1087209).
- CVE-2017-13220: An elevation of privilege vulnerability in the Upstream
 kernel bluez was fixed. (bnc#1076537).
- CVE-2017-11089: A buffer overread was observed in nl80211_set_station
 when user space application sends attribute
 NL80211_ATTR_LOCAL_MESH_POWER_MODE with data of size less than 4 bytes
 (bnc#1088261).
- CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function
 in the ALSA subsystem allowed attackers to gain privileges via
 unspecified vectors (bnc#1088260).
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel
 function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious
 NCPFS servers to crash the kernel or execute code (bnc#1086162).
- CVE-2017-18203: The dm_get_from_kobject function in drivers/md/dm.c
 allow local users to cause a denial of service (BUG) by leveraging a
 race condition with __dm_destroy during creation and removal of DM
 devices (bnc#1083242).
The following non-security bugs were fixed:
- Integrate fixes resulting from bsc#1088147 More info in the respective
 commit messages.
- KABI: x86/kaiser: properly align trampoline stack (bsc#1087260).
- kGraft: fix small race in reversion code (bsc#1083125).
- kabi/severities: Ignore kgr_shadow_* kABI changes
- kvm/x86: fix icebp instruction handling (bsc#1087088).
- livepatch: Allow to call a custom callback when freeing shadow variables
 (bsc#1082299 fate#313296).
- livepatch: Initialize shadow variables safely by a custom callback
