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 BASEDISCOVERLISTPROTOCOLS, 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 'loopnum_ret' is big enough.
Fix the validation avoiding the addition.
