CVE-2025-71083 Details
Description
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.
A vulnerability in the Linux kernel's Direct Rendering Manager (DRM) component, specifically within the Translation Table Mapping (TTM) subsystem, has been addressed. This vulnerability could lead to a NULL pointer dereference for buffer objects (BOs) that have been evicted and are not currently linked to a resource. When the 'devcoredump' process attempts to read the contents of all BOs for memory dumping, it must account for this possibility. In such cases, the absence of data is noted instead of the actual buffer contents, which could lead to unexpected behavior or crashes.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the official Linux kernel website.
