## Overview

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

nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet

syzbot reported the following uninit-value access issue [1][2]:

nci_rx_work() parses and processes received packet. When the payload
length is zero, each message type handler reads uninitialized payload
and KMSAN detects this issue. The receipt of a packet with a zero-size
payload is considered unexpected, and therefore, such packets should be
silently discarded.

This patch resolved this issue by checking payload size before calling
each message type handler codes.

## Affected

- `linux_kernel >= 3.2, < 4.19.312`
- `linux_kernel >= 4.20, < 5.4.274`
- `linux_kernel >= 5.5, < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.154`
- `linux_kernel >= 5.16, < 6.1.85`
- `linux_kernel >= 6.2, < 6.6.26`
- `linux_kernel >= 6.7, < 6.8.5`
- `linux_kernel = 6.9`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.5`
