In the Linux kernel, the following vulnerability has been resolved:

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.

No CVSS v4.0

No CVSS v3.1

No CVSS v3.0

No CVSS v2
