Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm/damon/reclaim: avoid divide-by-zero in damon_reclaim_apply_parameters()<br /> <br /> When creating a new scheme of DAMON_RECLAIM, the calculation of<br /> &amp;#39;min_age_region&amp;#39; uses &amp;#39;aggr_interval&amp;#39; as the divisor, which may lead to<br /> division-by-zero errors. Fix it by directly returning -EINVAL when such a<br /> case occurs.
