## Overview

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

sysctl: always initialize i_uid/i_gid

Always initialize i_uid/i_gid inside the sysfs core so set_ownership()
can safely skip setting them.

Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of
i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when
set_ownership() was not implemented. It also missed adjusting
net_ctl_set_ownership() to use the same default values in case the
computation of a better value failed.

## Affected

- `linux_kernel >= 4.9.187, < 4.10`
- `linux_kernel >= 4.14.135, < 4.15`
- `linux_kernel >= 4.19.61, < 4.20`
- `linux_kernel >= 5.1.20, < 5.2`
- `linux_kernel >= 5.2.3, < 5.10.224`
- `linux_kernel >= 5.11, < 5.15.165`
- `linux_kernel >= 5.16, < 6.1.104`
- `linux_kernel >= 6.2, < 6.6.45`
- `linux_kernel >= 6.7, < 6.10.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.10.3`
