## Overview

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

nvme: fix FDP fdpcidx bounds check

The fdpcidx bounds check sets n = NUMFDPC + 1 but used > instead of >=,
incorrectly accepting fdp_idx when it equals n (i.e. NUMFDPC + 1).

## Affected

- `Linux >= 30b5f20bb2ddab013035399e5c7e6577da49320a < 5e406928404d67a8da8aa3ae21732e1ea1a04118`
