Overview

CVE-2026-90428 is a known-severity vulnerability. It was published on September 17, 2026.

Technical 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.

How can CyberStrike help with CVE-2026-90428?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-90428 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
