Detail

In the Linux kernel, the following vulnerability has been resolved:

scsi: hisi_sas: Free irq vectors in order for v3 HW

If the driver probe fails to request the channel IRQ or fatal IRQ, the driver will free the IRQ vectors before freeing the IRQs in free_irq(), and this will cause a kernel BUG like this:

------------[ cut here ]------------ kernel BUG at drivers/pci/msi.c:369! Internal error: Oops - BUG: 0 [#1] PREEMPT SMP Call trace:
free_msi_irqs+0x118/0x13c
pci_disable_msi+0xfc/0x120
pci_free_irq_vectors+0x24/0x3c
hisi_sas_v3_probe+0x360/0x9d0 [hisi_sas_v3_hw]

kthread+0x180/0x190
ret_from_fork+0x10/0x20 ---[ end trace b88990335b610c11 ]---

So we use devm_add_action() to control the order in which we free the vectors.
