FKIE_CVE-2025-38044

Vulnerability from fkie_nvd - Published: 2025-06-18 10:15 - Updated: 2026-06-17 09:15
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: media: cx231xx: set device_caps for 417 The video_device for the MPEG encoder did not set device_caps. Add this, otherwise the video device can't be registered (you get a WARN_ON instead). Not seen before since currently 417 support is disabled, but I found this while experimenting with it.
