About this tag
The nfc subsystem tag on WindowsForum.com covers discussions about the Linux kernel's NFC stack, including security vulnerabilities and lifecycle fixes. Recent content focuses on CVE-2026-23330, a bug in the NFC subsystem where the kernel's nci_close_device() function now completes pending data exchanges before shutting down an NFC device. This prevents socket reference leaks that could occur if callbacks were not properly finalized. The tag is relevant for developers and system administrators working with NFC hardware on Linux, particularly those interested in kernel patches, device driver correctness, and security updates. Topics include NFC device close handling, in-flight exchange completion, and upstream stable patches.

    Linux NFC CVE-2026-23330 Fix: Complete In-Flight Exchange on Device Close

    The Linux kernel’s NFC stack is getting a small but important correctness fix in CVE-2026-23330, and the problem is exactly the kind of lifecycle bug that kernel maintainers try to stamp out early. In nci_close_device(), the kernel now completes any pending data exchange before the NFC device is...
