## Overview

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

inet: read sk->sk_family once in inet_recv_error()

inet_recv_error() is called without holding the socket lock.

IPv6 socket could mutate to IPv4 with IPV6_ADDRFORM
socket option and trigger a KCSAN warning.

## Affected

- `linux_kernel >= 3.18, < 4.19.307`
- `linux_kernel >= 4.20, < 5.4.269`
- `linux_kernel >= 5.5, < 5.10.210`
- `linux_kernel >= 5.11, < 5.15.149`
- `linux_kernel >= 5.16, < 6.1.78`
- `linux_kernel >= 6.2, < 6.6.17`
- `linux_kernel >= 6.7, < 6.7.5`
- `linux_kernel = 6.8`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.5`
