## Overview

In the Linux kernel, the following vulnerability has been resolved:

nfc: llcp: Fix use-after-free in llcp_sock_release()

llcp_sock_release() unconditionally unlinks the socket from the local
sockets list.  However, if the socket is still in connecting state, it
is on the connecting list.

Fix this by checking the socket state and unlinking from the correct list.

## Affected

- `linux_kernel >= 3.10.10, < 5.10.259`
- `linux_kernel >= 5.11, < 5.15.210`
- `linux_kernel >= 5.16, < 6.1.176`
- `linux_kernel >= 6.2, < 6.6.143`
- `linux_kernel >= 6.7, < 6.12.93`
- `linux_kernel >= 6.13, < 6.18.35`
- `linux_kernel >= 6.19, < 7.0.12`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.12`
