  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: arm_scpi: reject DVFS OPP count above MAX_DVFS_OPPS\n\nscpi_dvfs_get_info() already rejected a zero opp_count, but still trusted\nany larger value from the SCP firmware. 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.",
