  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: microread: validate target discovery payload lengths\n\nmicroread_target_discovered() parses target discovery payloads from\nskb->data according to the HCI gate. The fixed field offsets and UID\ncopies were checked only against the destination nfc_target buffers, not\nagainst the actual skb length.\n\nValidate that each gate-specific payload contains the fixed fields and\nUID bytes before reading or copying them.",
