Local VRAM corruption via unsynchronized initialization
Published Mar 27, 2025 · Updated Aug 5, 2026
Data corruption in Linux kernel 5.14 through 6.1.8 allows local users to corrupt SVM VRAM through AMD KFD memory access. The svm_range_vram_node_new() path schedules an asynchronous VRAM clear without waiting, so application writes can race unfinished initialization. Access to /dev/kfd on an AMD GPU host is required; the race can expose stale GPU data, crash compute workloads, or force GPU resets.

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.
Is a vulnerable build present?
