In the Linux kernel, the following vulnerability has been resolved:
scsi: pm8001: Use rollback index when freeing MSI-X vectors
pm8001_request_msix() unwinds previously registered handlers with free_irq() when request_irq() fails. The rollback loop uses the failing index i for every iteration instead of the already registered vector index j.
That passes the wrong IRQ/dev_id pair to free_irq() and leaves the earlier handlers installed. Use j for both pci_irq_vector() and the matching irq_vector entry in the rollback loop.
