The following security bugs were fixed:
CVE-2018-19824: A local user could exploit a use-after-free in the ALSA
 driver by supplying a malicious USB Sound device (with zero interfaces)
 that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).

CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping
 pagetable locks. If a syscall such as ftruncate() removed entries from
 the pagetables of a task that is in the middle of mremap(), a stale TLB
 entry could remain for a short time that permits access to a physical
 page after it has been released back to the page allocator and reused.
 (bnc#1113769).

CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in
 drivers/cdrom/cdrom.c could be used by local attackers to read kernel
 memory because a cast from unsigned long to int interferes with bounds
 checking. This is similar to CVE-2018-10940 and CVE-2018-16658
 (bnc#1113751).

CVE-2018-18445: Faulty computation of numeric bounds in the BPF verifier
 permitted out-of-bounds memory accesses because
 adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandled 32-bit
 right shifts (bnc#1112372).

CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are
 able to access pseudo terminals) to hang/block further usage of any
 pseudo terminal devices due to an EXTPROC versus ICANON confusion in
 TIOCINQ (bnc#1094825).

CVE-2017-18224: fs/ocfs2/aops.c omitted use of a semaphore and
 consequently had a race condition for access to the extent tree during
 read operations in DIRECT mode, which allowed local users to cause a
 denial of service (BUG) by modifying a certain e_cpos field
 (bnc#1084831).

CVE-2017-16533: The usbhid_parse function in
 drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of
 service (out-of-bounds read and system crash) or possibly have
 unspecified other impact via a crafted USB device (bnc#1066674).

The following non-security bugs were fixed:
ACPI/APEI: Handle GSIV and GPIO notification types (bsc#1115567).

ACPICA: Tables: Add WSMT support (bsc#1089350).

ACPI/IORT: Fix iort_get_platform_device_domain() uninitialized pointer
 value (bsc#1051510).

ACPI / LPSS: Add alternative ACPI HIDs for Cherry Trail DMA controllers
 (bsc#1051510).

ACPI, nfit: Fix ARS overflow continuation (bsc#1116895).

ACPI, nfit: Prefer _DSM over _LSR for namespace label reads
 (bsc#1112128).

ACPI/nfit, x86/mce: Handle only uncorrectable machine checks
 (bsc#1114279).

ACPI/nfit, x86/mce: Validate a MCE's address before using it
 (bsc#1114279).

ACPI / platform: Add SMB0001 HID to forbidden_id_list (bsc#1051510).

ACPI / processor: Fix the return value of acpi_processor_ids_walk()
 (bsc#1051510).

ACPI / watchdog: Prefer iTCO_wdt always when WDAT table uses RTC SRAM
 (bsc#1051510).
