In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: check ras and obj before dereference
nbio_v7_9_handle_ras_controller_intr_no_bifring() dereferences ras and obj without checking either for NULL. Both amdgpu_ras_get_context() and amdgpu_ras_find_obj() can return NULL, e.g. during the window between adev->nbio.ras being set (early in amdgpu_ras_init(), by design, to enable the fatal-error interrupt as soon as possible) and the PCIE_BIF ras object actually being created in RAS late_init. Any interrupt in that window crashes in hard-IRQ context.
This is analogous to commit d190b459b2a4 ("drm/amdgpu: the warning dereferencing obj for nbio_v7_4"), which fixed the same issue in the nbio_v7_4 handler.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
(cherry picked from commit c7071767a50a32ed727cf800ac84372429e3b4b3)
