## Overview

mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is not held during a PUD move.

## Affected

- `linux_kernel >= 5.0, < 5.4.211`
- `linux_kernel >= 5.5, < 5.10.137`
- `linux_kernel >= 5.11, < 5.12.18`
- `linux_kernel >= 5.13, < 5.13.3`
- `debian_linux = 10.0`
- `hci_baseboard_management_controller = h300s`
- `hci_baseboard_management_controller = h410c`
- `hci_baseboard_management_controller = h410s`
- `hci_baseboard_management_controller = h500s`
- `hci_baseboard_management_controller = h700s`
- `ubuntu_linux = 18.04`
- `ubuntu_linux = 20.04`
- `ubuntu_linux = 22.04`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.13.3`
