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

firmware: arm scpi: reject DVFS OPP count above MAX DVFS OPPS

scpi dvfs get info() already rejected a zero opp count, but still trusted any larger value from the SCP firmware. The shared-memory reply only holds MAX DVFS OPPS entries in buf.opps[]; a bigger count over-reads that array and then sizes the allocated OPP table incorrectly (garbage OPPs / OOB). The missing upper bound dates back to the original SCPI DVFS support.

Reject zero and out-of-range counts in one check and return -EINVAL.
