Vulnerability Details : CVE-2024-26945
In the Linux kernel, the following vulnerability has been resolved:
crypto: iaa - Fix nr_cpus < nr_iaa case
If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which
causes a divide-by-0 in rebalance_wq_table().
Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0
case, even though cpus_per_iaa is never used if nr_iaa == 0, for
paranoia.
