Details

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

mm/damon/reclaim: avoid divide-by-zero in damon_reclaim_apply_parameters()

When creating a new scheme of DAMON_RECLAIM, the calculation of 'min_age_region' 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.
