CVE-2022-49118
Estado: AnalizadaMedia (5.5)—
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:
So we use devm_add_action() to control the order in which we free the vectors.
