Description

CVE-2024-35907 is a vulnerability in the Linux kernel's mlxbf_gige driver, which supports Mellanox BlueField devices. The issue occurs during kdump operations when a receive (RX) interrupt is triggered before the driver fully initializes. This leads to a race condition that can result in a NULL pointer dereference, causing the system to crash.

A pending RX interrupt before the driver requests the IRQ can lead to an improper sequence of operations, resulting in the crash.

This flaw affects system stability during kdump operations, potentially causing kernel panics.
