     - kernel-linus-5.10.60-1.mga8
description: |
  This kernel-linus update is based on upstream 5.10.60 and fixes atleast
  the following security issues:

  A missing validation of the "int_ctl" VMCB field allows a malicious L1
  guest to enable AVIC support (Advanced Virtual Interrupt Controller)
  for the L2 guest. The L2 guest is able to write to a limited but still
  relatively large subset of the host physical memory, resulting in a
  crash of the entire system, leak of sensitive data or potential
  guest-to-host escape (CVE-2021-3653).

  A missing validation of the the "virt_ext" VMCB field and allows a
  malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and VLS
  (Virtual VMLOAD/VMSAVE) for the L2 guest. Under these circumstances,
  the L2 guest is able to run VMLOAD/VMSAVE unintercepted, and thus
  read/write portions of the host physical memory, resulting in a
  crash of the entire system, leak of sensitive data or potential
  guest-to-host escape (CVE-2021-3656).

  drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before
  5.13.3 makes it easier for attackers to defeat an ASLR protection
  mechanism because it prints a kernel pointer ().

  For other upstream fixes, see the referenced changelogs.

NVIDIA GM204 [GeForce GTX 970]

Linus kernel installed without problems.  Rebuilt nvidia-current and virtualbox driver.
NFS shares and NAS drive available at login.  No problems noted but bluetooth took a little time to set up.  This time a device search found the portable audio device and managed to pair.
Leaving this running for a few days.
