   An update that solves 16 vulnerabilities and has 98 fixes
   is now available.


   The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various
   security and bugfixes.

   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

     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.
   - CVE-2021-3656: Missing validation of the the `virt_ext` VMCB field and
     allows a malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and
     VLS for the L2 guest (bsc#1189400).
   - 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
   - CVE-2021-38205: drivers/net/ethernet/xilinx/xilinx_emaclite.c made it
     easier for attackers to defeat an ASLR protection mechanism because it

   - CVE-2021-3679: A lack of CPU resource in tracing module functionality
     was found in the way user uses trace ring buffer in a specific way. Only
     privileged local users (with CAP_SYS_ADMIN capability) could use this
     flaw to starve the resources causing denial of service (bnc#1189057).
   - CVE-2021-34556: Fixed side-channel attack via a Speculative Store Bypass
     via unprivileged BPF program that could have obtain sensitive
     information from kernel memory (bsc#1188983).
   - CVE-2021-35477: Fixed BPF stack frame pointer which could have been
