Official description

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] local_pci_probe+0x44/0xb0 work_for_cpu_fn+0x20/0x34 process_one_work+0x1d0/0x340 worker_thread+0x2e0/0x460 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.
