Severity CVSS v4.0:
Pending analysis
Type:
CWE-476 NULL Pointer Dereference
Publication date:

Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/ttm: Avoid NULL pointer deref for evicted BOs<br /> <br /> It is possible for a BO to exist that is not currently associated with a<br /> resource, e.g. because it has been evicted.<br /> <br /> When devcoredump tries to read the contents of all BOs for dumping, we need<br /> to expect this as well -- in this case, ENODATA is recorded instead of the<br /> buffer contents.
