The following security bugs were fixed:
CVE-2019-20095: mwifiex_tm_cmd in
 drivers/net/wireless/marvell/mwifiex/cfg80211.c had some error-handling
 cases that did not free allocated hostcmd memory. This will cause a
 memory leak and denial of service (bnc#1159909).

CVE-2019-20054: Fixed a NULL pointer dereference in
 drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links
 (bnc#1159910).

CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in
 net/dccp/feat.c, which may cause denial of service (bnc#1159908).

CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in
 drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service
 (bnc#1159841).

CVE-2019-19447: Mounting a crafted ext4 filesystem image, performing
 some operations, and unmounting can lead to a use-after-free in
 ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in
 fs/ext4/super.c (bnc#1158819).

CVE-2019-19319: A setxattr operation, after a mount of a crafted ext4
 image, can cause a slab-out-of-bounds write access because of an
 ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large
 old_size value is used in a memset call (bnc#1158021).

CVE-2019-19767: Fixed mishandling of ext4_expand_extra_isize, as
 demonstrated by use-after-free errors in __ext4_expand_extra_isize and
 ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c
 (bnc#1159297).

CVE-2019-18808: A memory leak in the ccp_run_sha_cmd() function in
 drivers/crypto/ccp/ccp-ops.c allowed attackers to cause a denial of
 service (memory consumption) (bnc#1156259).

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

CVE-2019-19066: A memory leak in the bfad_im_get_stats() function in
 drivers/scsi/bfa/bfad_attr.c allowed attackers to cause a denial of
 service (memory consumption) by triggering bfa_port_get_stats() failures
 (bnc#1157303).

CVE-2019-19051: There was a memory leak in the
 i2400m_op_rfkill_sw_toggle() function in
 drivers/net/wimax/i2400m/op-rfkill.c in the Linux kernel allowed
 attackers to cause a denial of service (memory consumption)
 (bnc#1159024).

CVE-2019-19338: There was an incomplete fix for Transaction Asynchronous
 Abort (TAA) (bnc#1158954).

CVE-2019-19332: There was an OOB memory write via
 kvm_dev_ioctl_get_cpuid (bnc#1158827).

CVE-2019-19537: There was a race condition bug that can be caused by a
 malicious USB device in the USB character device driver layer
 (bnc#1158904).

CVE-2019-19535: There was an info-leak bug that can be caused by a
 malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_fd.c
 driver (bnc#1158903).

CVE-2019-19527: There was a use-after-free bug that can be caused by a
 malicious ... [Please see the references for more information on the vulnerabilities]");
