CVE-2026-98806

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.
