    VirtualBox and 6.8 kernel

    Virtualbox from the repository works correctly with kernel 6.5.0-45Generic.

    However, with the 6.8.0-40 upgrade the kernel fails:

    UBSAN: array-index-out-of-bounds in /var/lib/dkms/virtualbox/6.1.50/build/vboxdrv/SUPDrvGip.c:637:59

    Re: VirtualBox and 6.8 kernel

    I stopped using regular VirtualBox after upgrading kernel beyond 6.2.x. Switched partially to virt-manager/libvirt/QEMU/KVM and partially to this third-party KVM backend for VirtualBox (based on VirtualBox 7.0.18). If you need to use 6.8.x kernel, would one or both of these options work for you?
