CVE-2023-52650

System crash via unchecked DSI device lookup

Published May 1, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel's Tegra DSI driver allows local users to crash affected systems during device probing. The DSI probe path fails to check whether of_find_device_by_node returned a platform device before dereferencing the result. Reachability requires a Tegra system using the DSI driver and a device-tree relationship whose host-device lookup fails; no confidentiality or integrity impact is reported.
