# CVE-2025-38363: drm/tegra: Fix a possible null pointer dereference

Status: published. Published: 2025-07-25. Updated: 2026-11-05.

In the Linux kernel, the following vulnerability has been resolved:

drm/tegra: Fix a possible null pointer dereference

In tegra_crtc_reset(), new memory is allocated with kzalloc(), but
no check is performed. Before calling __drm_atomic_helper_crtc_reset,
state should be checked to prevent possible null pointer dereference.
