Local system crash via task-info lifetime race
Published Jul 16, 2024 · Updated Aug 5, 2026
Race condition in the Linux kernel amdgpu driver before 6.9 allows local users to crash the system through concurrent VM teardown. Fault, reset, and diagnostic paths read task metadata embedded in an amdgpu VM without retaining its lifetime, so VM teardown can invalidate that data during access. Exploitation requires local low-privileged access and an active amdgpu virtual-memory context on supported AMD graphics hardware; the bounded impact is a host crash.

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?
