Details

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.
