## Overview

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

nfc: nci: Fix uninit-value in nci_rx_work

syzbot reported the following uninit-value access issue [1]

nci_rx_work() parses received packet from ndev->rx_q. It should be
validated header size, payload size and total packet size before
processing the packet. If an invalid packet is detected, it should be
silently discarded.

## Affected

- `linux_kernel >= 4.19.312, < 4.19.316`
- `linux_kernel >= 5.4.274, < 5.4.278`
- `linux_kernel >= 5.10.215, < 5.10.219`
- `linux_kernel >= 5.15.154, < 5.15.161`
- `linux_kernel >= 6.1.85, < 6.1.93`
- `linux_kernel >= 6.6.26, < 6.6.33`
- `linux_kernel >= 6.8.5, < 6.9.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.4`
