After reacquiring the locks it only checks\nthat the affinity is unchanged (target_vcpu == vgic_target_oracle(irq))\nbefore moving the interrupt, which assumes that an interrupt whose affinity\nis preserved is still queued on this vCPU's ap_list.\n\nThat assumption no longer holds if the interrupt is taken off the ap_list\nwhile the locks are dropped. vgic_flush_pending_lpis() removes the\ninterrupt from the list and sets irq->vcpu to NULL, but leaves\nenabled/pending/target_vcpu untouched. As the interrupt is still enabled\nand pending, vgic_target_oracle() returns the same target_vcpu, so the\naffinity check passes and list_del() is run a second time on an entry that\nhas already been removed.\n\nAlso check that the interrupt is still assigned to this vCPU\n(irq->vcpu == vcpu) before moving it.","state":0,"publishedAt":"2026-08-15T05:55:10.87+00:00","modifiedAt":"2026-10-16T18:55:15.201+00:00","affected":[{"ecosystem":"Vendor
