## Overview

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

nvme: fix bio leak on mapping failure

The local bio is always NULL, so we'd leak the bio if the integrity
mapping failed. Just get it directly from the request.

## Affected

- `linux_kernel >= 6.18, < 6.18.34`
- `linux_kernel >= 6.19, < 7.0.11`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.11`
