Local system crash via zero-length NFC packets
Published May 19, 2024 · Updated Aug 5, 2026
Use of uninitialized data in the Linux kernel NFC NCI receive path allows local users to crash the system with a zero-length packet. nci_rx_work passes zero-payload packets to message-type handlers, which read bytes from an uninitialized payload instead of rejecting the empty packet. Reachability requires local low-privilege access and an active NFC NCI path; the documented consequence is system availability loss without data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
