## Overview

A use-after-free flaw was found in the Linux kernel’s pipes functionality in how a user performs manipulations with the pipe post_one_notification() after free_pipe_info() that is already called. This flaw allows a local user to crash or potentially escalate their privileges on the system.

## Affected

- `linux_kernel >= 5.10.106, < 5.10.134`
- `linux_kernel >= 5.15.29, < 5.15.58`
- `linux_kernel >= 5.16.15, < 5.18.15`
- `h300s_firmware`
- `h500s_firmware`
- `h410c_firmware`
- `h700s_firmware`
- `h300e_firmware`
- `h500e_firmware`
- `h700e_firmware`
- `h410s_firmware`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.18.15`
