CVE-2022-50722

Local denial of service via NULL state dereference

Published Dec 24, 2025 · Updated Dec 24, 2025

NULL pointer dereference in the Linux kernel 5.14 through 6.0.5 allows local users to trigger an oops via IMGU selection IOCTLs. The IMGU driver obtains both active and try-selection pointers before choosing one, causing v4l2_subdev_get_try_crop() and related helpers to dereference a NULL sd_state. The path requires Intel IPU3 media hardware and the staging IMGU driver; the documented consequence is availability loss, not data access or modification.
