About this tag
CVE-2026-23330 is a Linux kernel vulnerability in the NFC (Near Field Communication) stack. The issue occurs in nci_close_device(), where a pending data exchange may not be completed before the NFC device is shut down, potentially leaving a socket reference behind. This lifecycle bug can cause a reference leak if the callback never finishes cleanly. The fix ensures that any in-flight exchange is completed before the device closes. This tag covers discussions about the vulnerability, its patch, and related kernel stability concerns for Linux systems.
