In the Linux kernel, the following vulnerability has been resolved:

moxart: fix potential use-after-free on remove path

was freed in moxart_remove(), so fix this by saving the base register of
the device and using it instead of the pointer dereference.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
