CVE-2026-80801

Estado: RecibidaSin puntuar—

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.
