Description
A vulnerability in the Linux kernel's drm/tegra component could lead to a null pointer dereference due to missing checks after memory allocation in tegra_crtc_reset(). This issue has been fixed by adding proper state checks before calling __drm_atomic_helper_crtc_reset. The flaw affects Linux kernel version 5.3 and has been resolved in subsequent commits.
