Description
A null pointer dereference vulnerability was found in the Linux kernel's amdgpu driver, specifically in the nbio_v7_9_handle_ras_controller_intr_no_bifring() function. The flaw occurs because the code dereferences pointers without checking if they are NULL, which can happen during a timing window in the initialization sequence. This can cause a crash in hard-IRQ context. The issue was fixed by adding proper NULL checks.
