The following security bugs were fixed:

CVE-2018-25020: Fixed an overflow in the BPF subsystem due to a
 mishandling of a long jump over an instruction sequence where inner
 instructions require substantial expansions into multiple BPF
 instructions. This affects kernel/bpf/core.c and net/core/filter.c
 (bnc#1193575).

CVE-2019-0136: Fixed insufficient access control in the Intel(R)
 PROSet/Wireless WiFi Software driver that may have allowed an
 unauthenticated user to potentially enable denial of service via
 adjacent access (bnc#1193157).

CVE-2020-35519: Fixed out-of-bounds memory access in x25_bind in
 net/x25/af_x25.c. A bounds check failure allowed a local attacker with a
 user account on the system to gain access to out-of-bounds memory,
 leading to a system crash or a leak of internal kernel information
 (bnc#1183696).

CVE-2021-0935: Fixed possible out of bounds write in ip6_xmit of
 ip6_output.c due to a use after free. This could lead to local
 escalation of privilege with System execution privileges needed. User
 interaction is not needed for exploitation (bnc#1192032).

CVE-2021-28711: Fixed issue with xen/blkfront to harden blkfront against
 event channel storms (XSA-391) (bsc#1193440).

CVE-2021-28712: Fixed issue with xen/netfront to harden netfront against
 event channel storms (XSA-391) (bsc#1193440).

CVE-2021-28713: Fixed issue with xen/console to harden hvc_xen against
 event channel storms (XSA-391) (bsc#1193440).

CVE-2021-28715: Fixed issue with xen/netback to do not queue unlimited
 number of packages (XSA-392) (bsc#1193442).

CVE-2021-33098: Fixed improper input validation in the Intel(R) Ethernet
 ixgbe driver that may have allowed an authenticated user to potentially
 cause denial of service via local access (bnc#1192877).

CVE-2021-3564: Fixed double-free memory corruption in the Linux kernel
 HCI device initialization subsystem that could have been used by
 attaching malicious HCI TTY Bluetooth devices. A local user could use
 this flaw to crash the system (bnc#1186207).

CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a
 race condition in gadget_dev_desc_UDC_show of configfs.c. This could
 lead to local information disclosure with System execution privileges
 needed. User interaction is not needed for exploitation (bnc#1193861).

CVE-2021-39657: Fixed out of bounds read due to a missing bounds check
 in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local
 information disclosure with System execution privileges needed
 (bnc#1193864).

CVE-2021-4002: Fixed incorrect TLBs flush in hugetlbfs after
 huge_pmd_unshare (bsc#1192946).

CVE-2021-4083: Fixed a read-after-free memory flaw inside the garbage
 collection for Unix domain socket file handlers when users call close()
 and fget() simultaneouslyand can ... [Please see the references for more information on the vulnerabilities]");
