CVE-2021-1107

Local code execution via nvmap write ioctls

Published Aug 11, 2021 · Updated Aug 3, 2024

Improper access control in NVIDIA SHIELD TV before SE 9.0 and Jetson Linux before 32.6.1 allows local users to execute code. The nvmap NVMAP_IOC_WRITE* ioctl paths accept operations without properly enforcing access controls on the caller. A low-privileged local account is required; exploitation permits code execution or system-wide integrity compromise, while NVIDIA does not disclose how the complete service interruption manifests.
