Go to dashboardWhen a static debug area fails to register on IBM s390 systems, the kernel leaves its area bounds set while clearing the pointers. Opening the debug view file or running debug_dump() then dereferences those NULL pointers and can crash the machine.

s390/debug: Fix NULL pointer dereference in debug_info_copy()
When debug_register_static() fails, it clears areas, active_pages and active_entries but leaves the area bounds unchanged. Copying such an area, either by opening its view file or via debug_dump(), makes debug_info_copy() dereference the NULL pointers.
Skip the copy loop when the source has no areas.
