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.
