Title
drm/ttm: Avoid NULL pointer deref for evicted BOs
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/ttm: Avoid NULL pointer deref for evicted BOs
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.
Severity ?
No CVSS data available.
