Description

Security update for the Linux Kernel The SUSE Linux Enterprise 12 SP1 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 in 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). - CVE-2017-13220: An elevation of privilege vulnerability in the Upstream kernel bluez was fixed. (bnc#1076537). - CVE-2017-11089: A buffer overread is 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 allowed 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). - dcache: Add cond_resched in shrink_dentry_list (bsc#1086194). - 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 (bsc#1082299 fate#313296). - usbnet: Fix a race between usbnet_stop() and the BH (bsc#1083275). - x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088). - x86/espfix: Fix return stack in do_double_fault() (bsc#1085279). - x86/kaiser: properly align trampoline stack (bsc#1087260). - x86/retpoline: do not perform thunk calls in ring3 vsyscall code (bsc#1085331).
