CVE-2022-49451
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.
