commitf66c53b3b9upstream. Defer unloading the MMU after a INVPCID until the instruction emulation has completed, i.e. until after RIP has been updated. On VMX, this is a benign bug as VMX doesn't touch the MMU when skipping an emulated instruction. However, on SVM, if nrip is disabled, the emulator is used to skip an instruction, which would lead to fireworks if the emulator were invoked without a valid MMU.
