## Overview

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

net: mscc: ocelot: Fix crash when adding interface under a lag

Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag")
fixed a similar issue in the lan966x driver caused by a NULL pointer dereference.
The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic
and is susceptible to the same crash.

This issue specifically affects the ocelot_vsc7514.c frontend, which leaves
unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as
it uses the DSA framework which registers all ports.

Fix this by checking if the port pointer is valid before accessing it.

## Affected

- `linux_kernel >= 5.12, < 5.15.198`
- `linux_kernel >= 5.16, < 6.1.161`
- `linux_kernel >= 6.2, < 6.6.121`
- `linux_kernel >= 6.7, < 6.12.66`
- `linux_kernel >= 6.13, < 6.18.6`
- `linux_kernel = 6.19`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.18.6`
