CVE-2026-23330

Summary: CVE-2026-23330 affects the Linux kernel NFC/NCI subsystem. The issue arises in nci_close_device() where pending data exchanges may not be completed before closing, allowing a leaking unreferenced socket object (example: 0xff1100000f435000, size 2048) and associated references. This could...
