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

  - KVM: SVM: Skip fastpath emulation on VM-Exit if next RIP isn't valid Skip the WRMSR and HLT fastpaths in     SVM's VM-Exit handler if the next RIP isn't valid, e.g. because KVM is running with nrips=false. SVM must     decode and emulate to skip the instruction if the CPU doesn't provide the next RIP, and getting the     instruction bytes to decode requires reading guest memory. Reading guest memory through the emulator can     fault, i.e. can sleep, which is disallowed since the fastpath handlers run with IRQs disabled. BUG:
