CVE-2026-90428

Estado: RecibidaSin puntuar—

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.
