Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.58

Description: A NULL pointer dereference issue was identified in the USB gadget driver's UVC (USB Video Class) handling of frame-based formats. Specifically, the color matching descriptor was not initialized, leading to a potential crash when userspace configuration does not explicitly define it. This occurs during the processing of uncompressed and MJPEG formats.

Recommendations: Linux kernel versions prior to 6.6.58 are affected. Update to version 6.6.58 or later to resolve this issue.
