Title
accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context()
Summary
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context()
Don't add BO to the vdev->bo_list in ivpu_gem_create_object().
When failure happens inside drm_gem_shmem_create(), the BO is not
fully created and ivpu_gem_bo_free() callback will not be called
causing a deleted BO to be left on the list.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
