Unspecified impact via incorrect migration cleanup
Published Sep 16, 2026 · Updated Sep 16, 2026
Improper error handling in Linux before 6.18.51 and 7.2.5 allows attackers to cause unspecified impact during failed VRAM-to-RAM migration. svm_migrate_copy_to_ram converts device DMA addresses to page references while cleaning up failed copies, so it can release or unlock the wrong system pages and omit matching DMA unmaps. The path requires AMD KFD device-to-system-memory migration to fail; the upstream record does not specify attacker access or the resulting security impact.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
