  - In the Linux kernel, the following vulnerability has been resolved: mm/damon/vaddr-test: fix memory leak
    in damon_do_test_apply_three_regions() When CONFIG_DAMON_VADDR_KUNIT_TEST=y and making
    CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y, the below memory leak is detected. Since
    commit 9f86d624292c (mm/damon/vaddr-test: remove unnecessary variables), the damon_destroy_ctx() is
    removed, but still call damon_new_target() and damon_new_region(), the damon_region which is allocated by
    kmem_cache_alloc() in damon_new_region() and the damon_target which is allocated by kmalloc in
    damon_new_target() are not freed. And the damon_region which is allocated in damon_new_region() in
    damon_set_regions() is also not freed. So use damon_destroy_target to free all the damon_regions and
    damon_target. unreferenced object 0xffff888107c9a940 (size 64): comm kunit_try_catch, pid 1069, jiffies
