The following security bugs were fixed:
CVE-2019-14615: An information disclosure vulnerability existed due to
 insufficient control flow in certain data structures for some Intel(R)
 Processors (bnc#1160195).

CVE-2019-14896: A heap-based buffer overflow vulnerability was found in
 the Marvell WiFi driver. A remote attacker could cause a denial of
 service (system crash) or, possibly execute arbitrary code, when the
 lbs_ibss_join_existing function is called after a STA connects to an AP
 (bnc#1157157).

CVE-2019-14897: A stack-based buffer overflow was found in the Marvell
 WiFi driver. An attacker is able to cause a denial of service (system
 crash) or, possibly execute arbitrary code, when a STA works in IBSS
 mode (allows connecting stations together without the use of an AP) and
 connects to another STA (bnc#1157155).

CVE-2019-16746: An issue was discovered in net/wireless/nl80211.c. It
 did not check the length of variable elements in a beacon head, leading
 to a buffer overflow (bnc#1152107).

CVE-2019-16994: A memory leak existed in sit_init_net() in
 net/ipv6/sit.c which might have caused denial of service, aka
 CID-07f12b26e21a (bnc#1161523).

CVE-2019-18808: A memory leak in drivers/crypto/ccp/ccp-ops.c allowed
 attackers to cause a denial of service (memory consumption), aka
 CID-128c66429247 (bnc#1156259).

CVE-2019-19036: An issue discovered in btrfs_root_node in
 fs/btrfs/ctree.c allowed a NULL pointer dereference because
 rcu_dereference(root->node) can be zero (bnc#1157692).

CVE-2019-19045: A memory leak in
 drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c allowed attackers to
 cause a denial of service (memory consumption) by triggering
 mlx5_vector2eqn() failures, aka CID-c8c2a057fdc7 (bnc#1161522).

CVE-2019-19051: A memory leak in drivers/net/wimax/i2400m/op-rfkill.c
 allowed attackers to cause a denial of service (memory consumption), aka
 CID-6f3ef5c25cc7 (bnc#1159024).

CVE-2019-19054: A memory leak in the cx23888_ir_probe() function in
 drivers/media/pci/cx23885/cx23888-ir.c allowed attackers to cause a
 denial of service (memory consumption) by triggering kfifo_alloc()
 failures, aka CID-a7b2df76b42b (bnc#1161518).

CVE-2019-19066: A memory leak in drivers/scsi/bfa/bfad_attr.c allowed
 attackers to cause a denial of service (memory consumption), aka
 CID-0e62395da2bd (bnc#1157303).

CVE-2019-19318: Mounting a crafted btrfs image twice could have caused a
 use-after-free (bnc#1158026).

CVE-2019-19319: A slab-out-of-bounds write access could have occurred
 when setxattr was called after mounting of a specially crafted ext4
 image (bnc#1158021).

CVE-2019-19332: An out-of-bounds memory write issue was found in the way
 the KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request
 to get CPUID features emulated by the KVM ... [Please see the references for more information on the vulnerabilities]");
