Doc Text: |
A use-after-free flaw was found in the pn533_usb_probe USB interface in the Linux kernel. If the driver registration fails it needs to do all the cleanup activity and free all the related resources. A malicious USB device can cause this process to fail, causing a use-after-free vulnerability. System availability is the highest threat with this vulnerability.
