In the Linux kernel, the following vulnerability has been resolved: usb: gadget: function: rndis: add length check for header Add a length check for the rndis header in rndis_rm_hdr, to ensure that MessageType, MessageLength, DataOffset, and DataLength fields are present before they are accessed.

A flaw was found in the Linux kernel's USB RNDIS gadget function. A missing length check for the RNDIS header in the `rndis_rm_hdr` function could allow an attacker to read data beyond the intended buffer. This out-of-bounds read vulnerability could lead to information disclosure or potentially a denial of service.
