What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic: Avoid double-deactivate of IRQs in the nested context In the nested state, the physical interrupt has already been deactivated through the HW bit in the LR. The extra deactivation would be harmless but can hit an errata case on AmpereOne, so avoid it here. On AmpereOne, deactivating a physical interrupt through ICC_DIR_EL1 or ICC_EOIR1_EL1 (depending on EOImode) which is not active, but is the highest priority pending interrupt causes the cpu to lose the interrupt pending state and also prevents the delivery of future interrupts.

Source: EUVD (ENISA), in the words of the advisory.
