CVE-2022-50759

Memory exhaustion via unreleased fwnode data

Published Dec 24, 2025 · Updated Dec 24, 2025

Memory leak in the ov5648 camera sensor driver in Linux 5.12 through 6.0.15 and 6.1 through 6.1.1 allows local users to consume kernel memory. The ov5648_remove function unregisters the subdevice but fails to call v4l2_fwnode_endpoint_free for sensor->endpoint, retaining its allocation. Triggering the leak requires local access able to unbind the ov5648 I2C device; repeated unbind operations consume additional kernel memory and can interrupt service.
