CVE 描述
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.
