CVE-2026-90428 | BDVDB-2026-376206 Detail

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.
