  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nocteontx2-pf: Fix aura BPID assignment when CONFIG_DCB is enabled\n\nPreviously, BPID assignment under CONFIG_DCB assumed\n`queue_to_pfc_map` was always initialized. For SDP VFs this leads to\ninvalid memory access as it was not initialized.\n\nThis patch adds a NULL check for `queue_to_pfc_map` before\ndereferencing it. Also, simplifies the logic by always assigning a\ndefault BPID first, then conditionally overriding it if CONFIG_DCB is\nenabled and the map exists.",
