     The following security bugs were fixed:

  - CVE-2021-3759: Unaccounted ipc objects in Linux kernel could have lead
       to breaking memcg limits and DoS attacks (bsc#1190115).

  - CVE-2021-38160: Data corruption or loss could be triggered by an
       untrusted device that supplies a buf- len value exceeding the buffer
       size in drivers/char/virtio_console.c (bsc#1190117)

  - CVE-2021-3640: Fixed a Use-After-Free vulnerability in function
       sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).

  - CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling
       (bsc#1190025).

  - CVE-2021-3743: Fixed OOB Read in qrtr_endpoint_post (bsc#1189883).

  - CVE-2021-3739: Fixed a NULL pointer dereference when deleting device by
       invalid id (bsc#1189832 ).

  - CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace
       can reveal files (bsc#1189706).

  - CVE-2021-3653: Missing validation of the `int_ctl` VMCB field and allows
       a malicious L1 guest to enable AVIC support for the L2 guest.
       (bsc#1189399).

  - CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h incorrectly computes the
       access permissions of a shadow page, leading to a missing guest
       protection page fault (bnc#1189262).

  - CVE-2021-38207: drivers/net/ethernet/xilinx/ll_temac_main.c allowed
       remote attackers to cause a denial of service (buffer overflow and
       lockup) by sending heavy network traffic for about ten minutes
       (bnc#1189298).

  - CVE-2021-38205: drivers/net/ethernet/xilinx/xilinx_emaclite.c made it
       easier for attackers to defeat an ASLR protection mechanism because it
       prints a kernel pointer (i.e., the real IOMEM pointer) (bnc#1189292).

  - CVE-2021-38204: drivers/usb/host/max3421-hcd.c allowed physically
       proximate attackers to cause a denial of service (use-after-free and
       panic) by removing a MAX-3421 USB device in certain situations
       (bnc#1189291).

  - CVE-2021-3640: A Use-After-Free vulnerability in function
       sco_sock_sendmsg() was fixed (bnc#1188172).

  - CVE-2021-34556: An unprivileged BPF program can obtain sensitive
       information from kernel memory via a Speculative Store Bypass
       side-channel attack because the protection mechanism neglects the
