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.

Executive Summary

This vulnerability involves the Linux kernel's drm/ttm component where a NULL pointer dereference can occur for evicted buffer objects (BOs). A BO may exist without being associated with a resource because it has been evicted. When devcoredump attempts to read all BO contents for dumping, it must handle this situation properly. The fix ensures that instead of dereferencing a NULL pointer, the system records ENODATA to indicate missing buffer contents.

Impact Analysis

If exploited, this vulnerability could cause a NULL pointer dereference in the Linux kernel, potentially leading to system crashes or instability when devcoredump reads evicted buffer objects. This could affect system reliability and availability.
