"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/core: validate ranges in damon_set_regions()\n\nDAMON core logic assumes zero length regions don't exist. However, a few\nDAMON API callers including DAMON_SYSFS, DAMON_RECLAIM and DAMON_LRU_SORT\nallow users to set empty monitoring target regions. This could result in\nWARN_ONCE() on CONFIG_DAMON_DEBUG_SANITY enabled kernel, and\ndivide-by-zero from damon_merge_two_regions().\n\nFor example, the WANR_ONCE() can be triggered like below.\n\n # grep DAMON_DEBUG_SANITY /boot/config-$(uname -r)\n # CONFIG_DAMON_DEBUG_SANITY=y\n # damo start\n # cd /sys/kernel/mm/damon/admin/kdamonds/0\n # echo 0 > contexts/0/targets/0/regions/0/start\n # echo 0 > contexts/0/targets/0/regions/0/end\n # echo commit > state\n # dmesg\n [....]\n [ 73.705780] ------------[ cut here ]------------\n [ 73.707552] start 0 >= end 0\n [ 73.708452] WARNING: mm/damon/core.c:359 at damon_new_region+0x6e/0x80, CPU#1: kdamond.0/758\n [...]\n\nAll DAMON API callers eventually use damon_set_regions() to setup the\nregions. Add the validation logic in the function."
