Summary
crypto: iaa - Fix nr_cpus < nr_iaa case
Details

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

crypto: iaa - Fix nrcpus < nriaa case

If nrcpus < nriaa, the calculated cpusperiaa will be 0, which causes a divide-by-0 in rebalancewqtable().

Make sure cpusperiaa is 1 in that case, and also in the nriaa == 0 case, even though cpusperiaa is never used if nriaa == 0, for paranoia.
