In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: f_rndis: Protect RNDIS options with mutex

The class/subclass/protocol options are suspectible to race conditions as they can be accessed concurrently through configfs.

Use existing mutex to protect these options. This issue was identified during code inspection.
