Spurious kernel warning via cancellation-context misclassification
Published Jan 15, 2025 · Updated May 11, 2026
Workqueue validation in affected Linux kernels allows local users to trigger a spurious warning during AMDGPU job scheduling. The check_flush_dependency helper applies flush-safety validation to cancel_work_sync and cancel_delayed_work_sync even though canceled work is already running or will never run. Reaching the condition requires a local AMDGPU job path; the kernel record characterizes cancellation as safe and documents no corruption, disclosure, or service interruption.

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.
