CVE-2026-68384

A flaw was found in the drm/xe/vf component of the Linux kernel. This vulnerability involves race conditions during the attachment and detachment of Cache Coherency System (CCS) batch buffers when Buffer Objects (BOs) are moved, particularly during Virtual Function (VF) migration events. These race conditions can lead to incorrect saving and restoring of CCS metadata or allow a migration event to race against an ongoing data transfer. The consequence is potential data integrity issues or system instability during VF migration.

This issue affects Intel Xe VF CCS batch buffers. BO move attach/detach races with in-flight CCS operations. Intel Xe VF configurations only.
