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

firmware: arm_scmi: Fix list protocols enumeration in the base protocol

While enumerating protocols implemented by the SCMI platform using BASE_DISCOVER_LIST_PROTOCOLS, the number of returned protocols is currently validated in an improper way since the check employs a sum between unsigned integers that could overflow and cause the check itself to be silently bypassed if the returned value 'loop_num_ret' is big enough.

Fix the validation avoiding the addition.
