In the Linux kernel, the following vulnerability has been resolved: mm/damon/reclaim: avoid divide-by-zero in damonreclaimapplyparameters() When creating a new scheme of DAMONRECLAIM, the calculation of 'minageregion' uses 'aggr_interval' as the divisor, which may lead to division-by-zero errors. Fix it by directly returning -EINVAL when such a case occurs.
