 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:KVM: arm64: Don t retire aborted MMIO instructionReturning an abort to the guest for an unsupported MMIO access is adocumented feature of the KVM UAPI. Nevertheless, it s clear that thisplumbing has seen limited testing, since userspace can trivially cause aWARN in the MMIO return:  WARNING: CPU: 0 PID: 30558 at arch/arm64/include/asm/kvm_emulate.h:536 kvm_handle_mmio_return+0x46c/0x5c4 arch/arm64/include/asm/kvm_emulate.h:536  Call trace:   kvm_handle_mmio_return+0x46c/0x5c4 arch/arm64/include/asm/kvm_emulate.h:536   kvm_arch_vcpu_ioctl_run+0x98/0x15b4 arch/arm64/kvm/arm.c:1133   kvm_vcpu_ioctl+0x75c/0xa78 virt/kvm/kvm_main.c:4487   __do_sys_ioctl fs/ioctl.c:51 [inline]   __se_sys_ioctl fs/ioctl.c:893 [inline]   __arm64_sys_ioctl+0x14c/0x1c8 fs/ioctl.c:893   __invoke_syscall arch/arm64/kernel/syscall.c:35 [inline]   invoke_syscall+0x98/0x2b8 arch/arm64/kernel/syscall.c:49   el0_svc_common+0x1e0/0x23c arch/arm64/kernel/syscall.c:132   do_el0_svc+0x48/0x58 arch/arm64/kernel/syscall.c:151   el0_svc+0x38/0x68 arch/arm64/kernel/entry-common.c:712   el0t_64_sync_handler+0x90/0xfc arch/arm64/kernel/entry-common.c:730   el0t_64_sync+0x190/0x194 arch/arm64/kernel/entry.S:598The splat is complaining that KVM is advancing PC while an exception ispending, i.e. that KVM is retiring the MMIO instruction despite apending synchronous external abort.
