CVE-2024-35907 is an initialization-ordering vulnerability in the Linux kernel mlxbf_gige Ethernet driver for Mellanox BlueField devices. During mlxbf_gige_open(), receive interrupts are registered before NAPI initialization is complete. A pending RX interrupt can fire immediately after request_irq() completes, causing receive processing to use uninitialized NAPI state and encounter a NULL pointer dereference. The demonstrated failure occurs when the kdump kernel loads the driver and brings its network interface up, resulting in a fatal exception and kernel panic.
