Doc Text:
A vulnerability was found in the Linux kernel's KVM component related to the LAPIC during the guest reboot process. This issue arises when the SET_LAPIC command is issued without exposing the tsc-deadline mode, leading to warnings and potential inconsistencies due to an unhandled preemption timer. This situation can disrupt the normal operation of virtual machines.
