In the Linux kernel, the following vulnerability has been resolved:
nfc: microread: validate target discovery payload lengths
microread target discovered() parses target discovery payloads from
skb->data according to the HCI gate. The fixed field offsets and UID
copies were checked only against the destination nfc target buffers, not
against the actual skb length.
Validate that each gate-specific payload contains the fixed fields and
UID bytes before reading or copying them.
