Summary

Security update for the Linux Kernel

Details

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 udlfbmmap 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 killsomethinginfo 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 kernelwait4 function in kernel/exit.c might allow local users to cause a denial of service by triggering an attempted use of the -INTMIN value (bnc#1089608).
CVE-2018-7757: Memory leak in the sassmpgetphyevents function in drivers/scsi/libsas/sasexpander.c allowed local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sasphy directory, as demonstrated by the /sys/class/sasphy/phy-1:0:12/invaliddword_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 nl80211setstation when user space application sends attribute NL80211ATTRLOCALMESHPOWER_MODE with data of size less than 4 bytes (bnc#1088261).
CVE-2017-0861: Use-after-free vulnerability in the sndpcminfo function in the ALSA subsystem allowed attackers to gain privileges via unspecified vectors (bnc#1088260).
CVE-2018-8822: Incorrect buffer length handling in the ncpreadkernel 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 dmgetfromkobject 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 kgrshadow* 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 (bsc#1082299 fate#313296).
x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
x86/kaiser: properly align trampoline stack (bsc#1087260).
x86/retpoline: do not perform thunk calls in ring3 vsyscall code (bsc#1085331).
