## Overview

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

aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts

This patch is against CVE-2023-6270. The description of cve is:

  A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
  kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
  `struct net_device`, and a use-after-free can be triggered by racing
  between the free on the struct and the access through the `skbtxq`
  global queue. This could lead to a denial of service condition or
  potential code execution.

In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
code is finished. But the net_device ifp will still be used in
later tx()->dev_queue_xmit() in kthread. Which means that the
dev_put(ifp) should NOT be called in the success path of skb
initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
use-after-free because the net_device is freed.

This patch removed the dev_put(ifp) in the success path in
aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

## Affected

- `linux_kernel >= 2.6.22, < 4.19.311`
- `linux_kernel >= 4.20, < 5.4.273`
- `linux_kernel >= 5.5, < 5.10.214`
- `linux_kernel >= 5.11, < 5.15.153`
- `linux_kernel >= 5.16, < 6.1.83`
- `linux_kernel >= 6.2, < 6.6.23`
- `linux_kernel >= 6.7, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
