## Overview

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

octeontx2-pf: Fix aura BPID assignment when CONFIG_DCB is enabled

Previously, BPID assignment under CONFIG_DCB assumed
`queue_to_pfc_map` was always initialized. For SDP VFs this leads to
invalid memory access as it was not initialized.

This patch adds a NULL check for `queue_to_pfc_map` before
dereferencing it. Also, simplifies the logic by always assigning a
default BPID first, then conditionally overriding it if CONFIG_DCB is
enabled and the map exists.

## Affected

- `Linux >= 184fb40f731bd3353b0887731f7caba66609e9cd < 59fbbded05e559675930fd521b8d62b72828b52d`
- `Linux >= 184fb40f731bd3353b0887731f7caba66609e9cd < 056994563935e049093f100efaad7e63ad113814`
- `Linux 22079d5ae4a33679150f7de89f4107f4e0446886`
- `Linux >= 6.14.9 < 6.15`
- `Linux 6.15`
