A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in
drivers/nfc/nfcmrvl/main.c can lead to use after free both read or write
when non synchronized between cleanup routine and firmware download
routine.

It was discovered that the Marvell NFC device driver implementation in the
Linux kernel did not properly perform memory cleanup operations in some
situations, leading to a use-after-free vulnerability. A local attacker
could possibly use this to cause a denial of service (system) or execute
arbitrary code.
