In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: vgic: Take a refcount on IRQs referenced by last lr irq
Referencing the last interrupt inserted in an LR is rather fragile, as
this interrupt can vanish if a concurrently unmapped LPI.
Solve this by bumping up the refcount on the interrupt when populating
last lr irq, and drop it at vgic prune ap list() time, when LPIs are
being reclaimed.
