Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 6.14.8. Affected by this issue is some unknown processing of the component media. The manipulation of the argument device_caps with an unknown input leads to a unknown weakness. The impact remains unknown. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2025-38044 since 04/16/2025. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 242347 (Oracle Linux 9 : Unbreakable Enterprise kernel (ELSA-2025-20480)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.4.294, 5.10.238, 5.15.185, 6.1.141, 6.6.93, 6.12.31 or 6.14.9 eliminates this vulnerability. Applying the patch 2ad41beb7df3bd63b209842d16765ec59dafe6e4/0884dd3abbe80307a2d4cbdbe5e312be164f8adb/c91447e35b9bea60bda4408c48e7891d14351021/9d1a5be86dbe074bd8dd6bdd63a99d6bb66d5930/5c9eca180a4235abd56cc7f7308ca72128d93dce/4731d5328f507ae8fd8a57abbca9119ec7a8d665/e43fd82bb2110bf9d13d800cdc49cceddfd0ede5/a79efc44b51432490538a55b9753a721f7d3ea42 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
