Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: uvc: Prevent buffer overflow in setup handler Setup function uvc_function_setup permits control transfer requests with up to 64 bytes of payload (UVC_MAX_REQUEST_SIZE), data stage handler for OUT transfer uses memcpy to copy req->actual bytes to uvc_event->data.data array of size 60. This may result in an overflow of 4 bytes.
