"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/lru_sort: avoid divide-by-zero in damon_lru_sort_apply_parameters()\n\nPatch series \"mm/damon: avoid divide-by-zero in DAMON module's parameters\napplication\".\n\nDAMON's RECLAIM and LRU_SORT modules perform no validation on\nuser-configured parameters during application, which may lead to\ndivision-by-zero errors.\n\nAvoid the divide-by-zero by adding validation checks when DAMON modules\nattempt to apply the parameters.\n\n\nThis patch (of 2):\n\nDuring the calculation of 'hot_thres' and 'cold_thres', either\n'sample_interval' or 'aggr_interval' is used as the divisor, which may\nlead to division-by-zero errors. Fix it by directly returning -EINVAL\nwhen such a case occurs. Additionally, since 'aggr_interval' is already\nrequired to be set no smaller than 'sample_interval' in damon_set_attrs(),\nonly the case where 'sample_interval' is zero needs to be checked."
