  "description": "In the Linux kernel, the following vulnerability has been resolved:  kunit: fix reference count leak in kfree_at_end  The reference counting issue happens in the normal path of kfree_at_end(). When kunit_alloc_and_get_resource() is invoked, the function forgets to handle the returned resource object, whose refcount increased inside, causing a refcount leak.  Fix this issue by calling kunit_alloc_resource() instead of kunit_alloc_and_get_resource().  Fixed the following when applying: Shuah Khan \u003Cskhan@linuxfoundation.org\u003E  CHECK: Alignment should match open parenthesis \u002B\tkunit_alloc_resource(test, NULL, kfree_res_free, GFP_KERNEL,  \t\t\t\t     (void *)to_free);",
