## Overview

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

fs/aio: Check IOCB_AIO_RW before the struct aio_kiocb conversion

The first kiocb_set_cancel_fn() argument may point at a struct kiocb
that is not embedded inside struct aio_kiocb. With the current code,
depending on the compiler, the req->ki_ctx read happens either before
the IOCB_AIO_RW test or after that test. Move the req->ki_ctx read such
that it is guaranteed that the IOCB_AIO_RW test happens first.

## Affected

- `linux_kernel >= 4.19.308, < 4.19.312`
- `linux_kernel >= 5.4.270, < 5.4.274`
- `linux_kernel >= 5.10.211, < 5.10.215`
- `linux_kernel >= 5.15.150, < 5.15.154`
- `linux_kernel >= 6.1.80, < 6.1.84`
- `linux_kernel >= 6.6.19, < 6.6.24`
- `linux_kernel >= 6.7.7, < 6.7.12`
- `linux_kernel = 6.8`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.12`
