Linux Kernel Vulnerability in Tegra Graphics Driver by NVIDIA

CVE-2026-80883

What is CVE-2026-80883?

A vulnerability in the NVIDIA Tegra graphics driver within the Linux kernel allows the host1x client to be registered prior to the initialization of the address register map. This misordering can lead to userspace submitting jobs before the necessary register map is fully prepared, potentially causing undefined behavior. To resolve this issue, the register initialization process must be conducted before the registration of the host1x client, ensuring that the system is stable and functioning as intended.
