## Overview

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

af_packet: avoid erroring out after sock_init_data() in packet_create()

After sock_init_data() the allocated sk object is attached to the provided
sock object. On error, packet_create() frees the sk object leaving the
dangling pointer in the sock object on return. Some other code may try
to use this pointer and cause use-after-free.

## Affected

- `linux_kernel < 5.4.287`
- `linux_kernel >= 5.5, < 5.10.231`
- `linux_kernel >= 5.11, < 5.15.174`
- `linux_kernel >= 5.16, < 6.1.120`
- `linux_kernel >= 6.2, < 6.6.66`
- `linux_kernel >= 6.7, < 6.12.5`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.12.5`
