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.
