Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contained an issue in the uvcvideo driver related to handling of Universal Video Class (UVC) entities. Specifically, the driver did not properly mark invalid entities with the ID UVC INVALID ENTITY ID, as required by the UVC 1.1+ specification. This could lead to warnings and potential issues when processing video streams, particularly in scenarios involving chains of entities referencing themselves or invalid source IDs. The issue was identified through syzkaller testing, which revealed stack traces indicating problems with pad link creation and entity initialization.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
