Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - KVM: x86: Load DR6 with guest value only before entering .vcpu_run() loop Move the conditional loading of     hardware DR6 with the guest's DR6 value out of the core .vcpu_run() loop to fix a bug where KVM can load     hardware with a stale vcpu->arch.dr6. When the guest accesses a DR and host userspace isn't debugging the     guest, KVM disables DR interception and loads the guest's values into hardware on VM-Enter and saves them     on VM-Exit. This allows the guest to access DRs at will, e.g. so that a sequence of DR accesses to     configure a breakpoint only generates one VM-Exit. For DR0-DR3, the logic/behavior is identical between     VMX and SVM, and also identical between KVM_DEBUGREG_BP_ENABLED (userspace debugging the guest) and     KVM_DEBUGREG_WONT_EXIT (guest using DRs), and so KVM handles loading DR0-DR3 in common code, _outside_ of     the core kvm_x86_ops.vcpu_run() loop. But for DR6, the guest's value doesn't need to be loaded into     hardware for KVM_DEBUGREG_BP_ENABLED, and SVM provides a dedicated VMCB field whereas VMX requires     software to manually load the guest value, and so loading the guest's value into DR6 is handled by     {svm,vmx}_vcpu_run(), i.e. is done _inside_ the core run loop. Unfortunately, saving the guest values on     VM-Exit is initiated by common x86, again outside of the core run loop. If the guest modifies DR6 (in     hardware, when DR interception is disabled), and then the next VM-Exit is a fastpath VM-Exit, KVM will     reload hardware DR6 with vcpu->arch.dr6 and clobber the guest's actual value. The bug shows up primarily     with nested VMX because KVM handles the VMX preemption timer in the fastpath, and the window between     hardware DR6 being modified (in guest context) and DR6 being read by guest software is orders of magnitude     larger in a nested setup. E.g. in non-nested, the VMX preemption timer would need to fire precisely     between #DB injection and the #DB handler's read of DR6, whereas with a KVM-on-KVM setup, the window where     hardware DR6 is dirty extends all the way from L1 writing DR6 to VMRESUME (in L1).
