Overview
CVE-2026-80801 is a known-severity vulnerability. It was published on September 4, 2026.
Technical description
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.
Remediation

How can CyberStrike help with CVE-2026-80801?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-80801 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
