## Overview

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

selinux: Add boundary check in put_entry()

Just like next_entry(), boundary check is necessary to prevent memory
out-of-bound access.

## Affected

- `linux_kernel >= 2.6.37, < 4.14.291`
- `linux_kernel >= 4.15, < 4.19.256`
- `linux_kernel >= 4.20, < 5.4.211`
- `linux_kernel >= 5.5, < 5.10.137`
- `linux_kernel >= 5.11, < 5.15.61`
- `linux_kernel >= 5.16, < 5.18.18`
- `linux_kernel >= 5.19, < 5.19.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19.2`
