## Overview

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

ACPICA: Refuse to evaluate a method if arguments are missing

As reported in [1], a platform firmware update that increased the number
of method parameters and forgot to update a least one of its callers,
caused ACPICA to crash due to use-after-free.

Since this a result of a clear AML issue that arguably cannot be fixed
up by the interpreter (it cannot produce missing data out of thin air),
address it by making ACPICA refuse to evaluate a method if the caller
attempts to pass fewer arguments than expected to it.

## Affected

- `linux_kernel < 5.4.296`
- `linux_kernel >= 5.5, < 5.10.240`
- `linux_kernel >= 5.11, < 5.15.187`
- `linux_kernel >= 5.16, < 6.1.144`
- `linux_kernel >= 6.2, < 6.6.97`
- `linux_kernel >= 6.7, < 6.12.37`
- `linux_kernel >= 6.13, < 6.15.6`
- `linux_kernel = 6.16`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.15.6`
