CVE-2020-5967

Local denial of service via UVM race

Published Jun 25, 2020 · Updated Aug 4, 2024

Race condition in the UVM driver in NVIDIA Linux GPU Display Driver allows local users to cause a system denial of service. NVIDIA has not disclosed the shared resource, competing UVM operations, or synchronization error that triggers the race. Exploitation requires local low-privilege access; the documented consequence is service interruption only, with no confidentiality or integrity impact.
