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-2020-27673: Fixed an issue in Xen where a guest OS users could have
caused a denial of service (host OS hang) via a high rate of events to
dom0 (bnc#1177411, bnc#1184583).
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-2020-36322: Fixed an issue inside the FUSE filesystem implementation
where fuse_do_getattr() calls make_bad_inode() in inappropriate
situations, could have caused a system crash. NOTE: the original fix for
this vulnerability was incomplete, and its incompleteness is tracked as
CVE-2021-28950 (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 ... [Please see the references for more information on the vulnerabilities]");
