A flaw was found in the Linux kernel's Near Field Communication (NFC) subsystem. A reference counting error in the nfc_get_local_general_bytes() function causes memory to be freed prematurely while callers still access the returned pointer. A local attacker could exploit this use-after-free vulnerability during NFC operations to cause a denial of service (DoS) or potentially execute arbitrary code.
