The shared-memory reply only holds\nMAX_DVFS_OPPS entries in buf.opps[]; a bigger count over-reads that array\nand then sizes the allocated OPP table incorrectly (garbage OPPs / OOB).\nThe missing upper bound dates back to the original SCPI DVFS support.\n\nReject zero and out-of-range counts in one check and return -EINVAL.","categories":["Operating
