CVE-2024-26742

In the Linux kernel, the following vulnerability has been resolved: scsi:
smartpqi: Fix disable_managed_interrupts Correct blk-mq registration issue
with module parameter disable_managed_interrupts enabled. When we turn off
the default PCI_IRQ_AFFINITY flag, the driver needs to register with blk-mq
using blk_mq_map_queues(). The driver is currently calling
blk_mq_pci_map_queues() which results in a stack trace and possibly
undefined behavior. Stack Trace: [ 7.860089] scsi host2: smartpqi [
