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 <skhan@linuxfoundation.org>
CHECK: Alignment should match open parenthesis
+ kunit_alloc_resource(test, NULL, kfree_res_free, GFP_KERNEL,
(void *)to_free);
CVSS
No CVSS.
