The following security bugs were fixed:

CVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks
 validation of an sk_family field, which might allow attackers to trigger
 kernel stack corruption via crafted system calls (bsc#1167629).

CVE-2020-8647: There was a use-after-free vulnerability in the
 vc_do_resize function in drivers/tty/vt/vt.c (bsc#1162929).

CVE-2020-8649: There was a use-after-free vulnerability in the
 vgacon_invert_region function in drivers/video/console/vgacon.c
 (bsc#1162931).

CVE-2020-9383: An issue was discovered set_fdc in drivers/block/floppy.c
 leads to a wait_til_ready out-of-bounds read because the FDC index is
 not checked for errors before assigning it (bsc#1165111).

CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function
 in kernel/trace/blktrace.c (bsc#1159285).

CVE-2020-11608: Fixed a NULL pointer dereferences in
 ov511_mode_init_regs and ov518_mode_init_regs when there are zero
 endpoints (bsc#1168829).

CVE-2020-8648: There was a use-after-free vulnerability in the
 n_tty_receive_buf_common function in drivers/tty/n_tty.c (bsc#1162928).

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

CVE-2019-14897: A stack-based buffer overflow was found in the Marvell
 WiFi chip driver. An attacker is able to cause a denial of service or
 possibly execute arbitrary code, when a STA works in IBSS mode and
 connects to another STA (bsc#1157155).

CVE-2019-18675: Fixed an Integer Overflow in cpia2_remap_buffer in
 drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap
 implementation. This allowed local users to obtain read and write
 permissions on kernel physical pages, which can possibly result in a
 privilege escalation (bsc#1157804).

CVE-2019-19965: Fixed a NULL pointer dereference in
 drivers/scsi/libsas/sas_discover.c because of mishandling of port
 disconnection during discovery, related to a PHY down race condition
 (bsc#1159911).

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 by triggering bfa_port_get_stats() failures (bsc#1157303).

CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in
 net/dccp/feat.c, which may cause denial of service (bsc#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
 (bsc#1159841).

CVE-2019-19532: Fixed multiple out-of-bounds write bugs that can be
 caused by a malicious USB device (bsc#1158824).

CVE-2019-19523: Fixed a use-after-free bug that can be ... [Please see the references for more information on the vulnerabilities]");
