Detail

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

CHECK: Alignment should match open parenthesis + kunit_alloc_resource(test, NULL, kfree_res_free, GFP_KERNEL,
(void *)to_free);
