## Overview

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

octeontx2-af: Fix mcam entry resource leak

The teardown sequence in FLR handler returns if no NIX LF
is attached to PF/VF because it indicates that graceful
shutdown of resources already happened. But there is a
chance of all allocated MCAM entries not being freed by
PF/VF. Hence free mcam entries even in case of detached LF.

## Affected

- `Linux >= c554f9c1574e022821260b24b043a4277e8ec5d8 < dc5be2d4f9285efe0d16f1bf00250df91d05d809`
- `Linux >= c554f9c1574e022821260b24b043a4277e8ec5d8 < cc32347f48111eea8d0165538c92aca92ede83f6`
- `Linux >= c554f9c1574e022821260b24b043a4277e8ec5d8 < 3f8fe40ab7730cf8eb6f8b8ff412012f7f6f8f48`
- `Linux 5.0`
