CVE-2024-26945 Information

Description

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.
