In the Linux kernel, the following vulnerability has been resolved:
mm/damon/lru_sort: avoid divide-by-zero in damon_lru_sort_apply_parameters()
Patch series "mm/damon: avoid divide-by-zero in DAMON module's parameters
application".
DAMON's RECLAIM and LRU_SORT modules perform no validation on
user-configured parameters during application, which may lead to
division-by-zero errors.
Avoid the divide-by-zero by adding validation checks when DAMON modules
attempt to apply the parameters.
This patch (of 2):
During the calculation of 'hot_thres' and 'cold_thres', either
'sample_interval' or 'aggr_interval' is used as the divisor, which may
lead to division-by-zero errors. Fix it by directly returning -EINVAL
when such a case occurs. Additionally, since 'aggr_interval' is already
required to be set no smaller than 'sample_interval' in damon_set_attrs(),
only the case where 'sample_interval' is zero needs to be checked.
