An information disclosure vulnerability was found in the Linux kernel. The RNDIS USB gadget lacks validation of the size of the RNDIS_MSG_SET command. This flaw allows a local attacker to dump contents of kernel memory space via a packet filter update mechanism and potentially extract sensitive information.
