CVE-2022-48948: usb: gadget: uvc: Prevent buffer overflow in setup handler
First published: Mon Oct 21 2024(Updated: )
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.
