The following security bugs were fixed:
CVE-2018-16597: Incorrect access checking in overlayfs mounts could have
 been used by local attackers to modify or truncate files in the
 underlying filesystem (bnc#1106512).

CVE-2018-14613: Prevent invalid pointer dereference in io_ctl_map_page()
 when mounting and operating a crafted btrfs image, caused by a lack of
 block group item validation in check_leaf_item (bsc#1102896)

CVE-2018-14617: Prevent NULL pointer dereference and panic in
 hfsplus_lookup() when opening a file (that is purportedly a hard link)
 in an hfs+ filesystem that has malformed catalog data, and is mounted
 read-only without a metadata directory (bsc#1102870)

CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in
 yurex_read allowed local attackers to use user access read/writes to
 crash the kernel or potentially escalate privileges (bsc#1106095)

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-2018-7480: The blkcg_init_queue function allowed local users to
 cause a denial of service (double free) or possibly have unspecified
 other impact by triggering a creation failure (bsc#1082863).

CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c
 mishandled sequence number overflows. An attacker can trigger a
 use-after-free (and possibly gain privileges) via certain thread
 creation, map, unmap, invalidation, and dereference operations
 (bnc#1108399).

The following non-security bugs were fixed:
asm/sections: add helpers to check for section data (bsc#1063026).

ASoC: wm8994: Fix missing break in switch (bnc#1012382).

block: bvec_nr_vecs() returns value for wrong slab (bsc#1082979).

bpf: fix overflow in prog accounting (bsc#1012382).

btrfs: Add checker for EXTENT_CSUM (bsc#1102882, bsc#1102896,
 bsc#1102879, bsc#1102877, bsc#1102875,).

btrfs: Add sanity check for EXTENT_DATA when reading out leaf
 (bsc#1102882, bsc#1102896, bsc#1102879, bsc#1102877, bsc#1102875,).

btrfs: Check if item pointer overlaps with the item itself (bsc#1102882,
 bsc#1102896, bsc#1102879, bsc#1102877, bsc#1102875,).

btrfs: Check that each block group has corresponding chunk at mount time
 (bsc#1102882, bsc#1102896, bsc#1102879, bsc#1102877, bsc#1102875,).

btrfs: Introduce mount time chunk dev extent mapping check
 (bsc#1102882, bsc#1102896, bsc#1102879, bsc#1102877, bsc#1102875,).

btrfs: Move leaf and node validation checker to tree-checker.c
 (bsc#1102882, bsc#1102896, bsc#1102879, bsc#1102877, bsc#1102875,).
