Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A buffer overflow vulnerability in multiple NETGEAR router models allows remote attackers to execute arbitrary code or cause denial of service via crafted network requests. The vulnerability affects the listed device models running firmware versions prior to the specified thresholds. The CVSS 7.8 indicates network-exploitable, low-complexity attack requiring no authentication.

MitigationUpgrade affected NETGEAR devices to the patched firmware versions specified in the advisory. If firmware updates are unavailable, restrict network access to trusted users and disable remote management interfaces exposed to untrusted networks.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify your NETGEAR router model
    Locate the model number on the device label or log into the router web interface (typically 192.168.1.1) and check the status or administration page for the model name
    Affected if The model is one of: D6200, D7000, Jnr1010, Jr6150, Jwnr2010, PR2000, R6020, or R6050
  2. Check the installed firmware version
    In the router web interface, navigate to the Administration or Firmware Upgrade section and locate the current firmware version displayed
    Affected if The displayed firmware version is below the threshold for your specific model (D6200: 1.1.00.24, D7000: 1.0.1.52, Jnr1010: 1.1.0.44, Jr6150: 1.0.1.12, Jwnr2010: 1.1.0.44, PR2000: 1.0.0.20, R6020: 1.0.0.26, R6050: 1.0.1.12)
  3. Confirm network exposure of the router management interface
    Verify whether the router admin web interface is accessible from the WAN/internet or if remote management is enabled in the router settings
    Affected if The router management interface is reachable from untrusted networks, increasing the likelihood of remote exploitation

You are affected if you own one of the listed NETGEAR models and your current firmware version is below the specified threshold for that model.
