Description
In the Linux kernel, the following vulnerability has been resolved:
clk: scpi: bound-check DVFS index in scpi_dvfs_recalc_rate
dvfs_get_idx() may return an out-of-range index if the SCP firmware is
buggy or returns a stale value. Only negative indexes were rejected, so a
large index walked past info->opps and could treat garbage as a clock rate
(KASAN OOB / wrong frequency to consumers). The missing upper bound dates
back to the original SCPI clock driver.
Treat indexes >= opp count as invalid and return 0, same as idx < 0.
