drm/ttm: Avoid NULL pointer deref for evicted BOs
Published Jan 13, 2026

MEDIUMCVSS 3.1
EPSS 0.13%
Description
It is possible for a BO to exist that is not currently associated with a resource, e.g. because it has been evicted.
When devcoredump tries to read the contents of all BOs for dumping, we need to expect this as well -- in this case, ENODATA is recorded instead of the buffer contents.
