GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2026-80801

Vulnerability from fkie_nvd - Published: 2026-09-04 16:18 - Updated: 2026-09-04 16:18
Severity
Summary
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.
