AI-suggested

A patch is available and has been applied in the Linux kernel source code. Users and administrators should update to a fixed kernel version containing the referenced commits to remediate this issue. Since this is a kernel-level fix, applying the official kernel update is the recommended mitigation.

Description

A vulnerability in the Linux kernel NFC subsystem (nci) was fixed by ensuring that any pending data exchange is completed before the device is closed. The flaw involved incomplete handling of data exchange callbacks holding socket references, which could lead to resource leaks.
