Overview

What is CVE-2026-92490?

In the Linux kernel, the following vulnerability has been resolved:

firmware: arm_scmi: Unrequest devices if driver registration fails

scmi_driver_register() requests protocol devices before registering the driver. If driver_register() fails, those requests remain in the global IDR and retain pointers to the module's ID table.

Once the failed module load releases that storage, later request matching or SCMI device creation can dereference the stale pointers.

Unrequest the complete protocol table before returning the registration failure. At this point table registration succeeded, so every entry is owned by the current registration attempt.
