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.
