CVE-2021-1069

Local denial of service via NVHost null pointer

Published Jan 20, 2021 · Updated Aug 3, 2024

Null pointer dereference in NVIDIA SHIELD TV before 8.2.2 allows local users to interrupt service via crafted NVHost input. The NVHost function dereferences a null pointer, triggering an abnormal reboot and possible data loss. Physical access or an equivalent local execution path is required; the documented impact is service interruption and data loss rather than confidentiality loss.
