Certain D-Link, Edimax, NETGEAR, TP-Link, Tenda, and Western Digital devices are affected by an integer overflow by an unauthenticated attacker. Remote code execution from the WAN interface (TCP port 20005) cannot be ruled out; however, exploitability was judged to be of "rather significant complexity" but not "impossible." The overflow is in SoftwareBus_dispatchNormalEPMsgOut in the KCodes NetUSB kernel module. Affected NETGEAR devices are D7800 before 1.0.1.68, R6400v2 before 1.0.4.122, and R6700v3 before 1.0.4.122.

An exploitable information disclosure vulnerability exists in the KCodes NetUSB.ko kernel module that enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. An unauthenticated, remote attacker can craft and send a packet containing an opcode that will trigger the kernel module to return several addresses. One of which can be used to calculate the dynamic base address of the module for further exploitation.

An exploitable arbitrary memory read vulnerability exists in the KCodes NetUSB.ko kernel module which enables the ReadySHARE Printer functionality of at least two NETGEAR Nighthawk Routers and potentially several other vendors/products. A specially crafted index value can cause an invalid memory read, resulting in a denial of service or remote information disclosure. An unauthenticated attacker can send a crafted packet on the local network to trigger this vulnerability.
