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.
