Description
Description
In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Don't run the error ISR before probe sets up vintfs
__tegra241_cmdqv_probe() requests the error IRQ before it has allocated the
cmdqv->vintfs array and set cmdqv->num_vintfs. A CMDQV left enabled with a
latched error across a kexec fires the IRQ as soon as it is requested, and
tegra241_cmdqv_isr() then walks the uninitialized cmdqv->vintfs array.
Request the IRQ only after cmdqv->vintfs is allocated and zeroed, so that
a latched interrupt firing early runs the ISR against a valid array of NULL
slots that it safely skips.
