The following security bugs were fixed:

CVE-2020-36312: Fixed an issue in virt/kvm/kvm_main.c that had a
 kvm_io_bus_unregister_dev memory leak upon a kmalloc failure
 (bnc#1184509).

CVE-2021-29650: Fixed an issue inside the netfilter subsystem that
 allowed attackers to cause a denial of service (panic) because
 net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a
 full memory barrier upon the assignment of a new table value
 (bnc#1184208).

CVE-2021-29154: Fixed BPF JIT compilers that allowed to execute
 arbitrary code within the kernel context (bnc#1184391).

CVE-2020-25673: Fixed NFC endless loops caused by repeated
 llcp_sock_connect() (bsc#1178181).

CVE-2020-25672: Fixed NFC memory leak in llcp_sock_connect()
 (bsc#1178181).

CVE-2020-25671: Fixed NFC refcount leak in llcp_sock_connect()
 (bsc#1178181).

CVE-2020-25670: Fixed NFC refcount leak in llcp_sock_bind()
 (bsc#1178181).

CVE-2021-28950: Fixed an issue in fs/fuse/fuse_i.h where a 'stall on
 CPU' could have occurred because a retry loop continually finds the same
 bad inode (bnc#1184194, bnc#1184211).

CVE-2021-30002: Fixed a memory leak issue when a webcam device exists
 (bnc#1184120).

CVE-2021-3483: Fixed a use-after-free bug in nosy_ioctl() (bsc#1184393).

CVE-2021-20219: Fixed a denial of service vulnerability in
 drivers/tty/n_tty.c of the Linux kernel. In this flaw a local attacker
 with a normal user privilege could have delayed the loop and cause a
 threat to the system availability (bnc#1184397).

CVE-2021-29265: Fixed an issue in usbip_sockfd_store in
 drivers/usb/usbip/stub_dev.c that allowed attackers to cause a denial of
 service (GPF) because the stub-up sequence has race conditions during an
 update of the local and shared status (bnc#1184167).

CVE-2021-29264: Fixed an issue in
 drivers/net/ethernet/freescale/gianfar.c in the Freescale Gianfar
 Ethernet driver that allowed attackers to cause a system crash because a
 negative fragment size is calculated in situations involving an rx queue
 overrun when jumbo packets are used and NAPI is enabled (bnc#1184168).

CVE-2021-28972: Fixed an issue in drivers/pci/hotplug/rpadlpar_sysfs.c
 where the RPA PCI Hotplug driver had a user-tolerable buffer overflow
 when writing a new device name to the driver from userspace, allowing
 userspace to write data to the kernel stack frame directly. This occurs
 because add_slot_store and remove_slot_store mishandle drc_name '\0'
 termination (bnc#1184198).

CVE-2021-28660: Fixed rtw_wx_set_scan in
 drivers/staging/rtl8188eu/os_dep/ioctl_linux.c that allowed writing
 beyond the end of the ssid array (bnc#1183593).

CVE-2020-0433: Fixed blk_mq_queue_tag_busy_iter of blk-mq-tag.c, where a
 possible use after free due to improper locking could have happened.
 This could have led to local ... [Please see the references for more information on the vulnerabilities]");
