In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pci: Reject adapter interrupt forwarding if already enabled The MPCIFC instruction doesn't allow registering adapter interrupts without first unregistering.

This also fixes overwriting and thus leaking resources when the ioctl is called multiple times for the same device.
