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

firmware: arm_scmi: Harden accesses to the reset domains

Accessing reset domains descriptors by the index upon the SCMI drivers
requests through the SCMI reset operations interface can potentially
lead to out-of-bound violations if the SCMI driver misbehave.

Add an internal consistency check before any such domains descriptors
accesses.
