Dates and sources
Calculated ASUS’s firmware page marks this model as end-of-life without a date, so I use the release date of its final firmware (May 7, 2026).

Key dates
- Release
- By July 2018 at the latestThe maker gives no launch date. This is the month of the first update: the launch was in it or before.

- May 7, 2026 · version 3.0.0.4.386_52334
- End of support
- May 7, 2026 · calculated by us from the maker’s dataHow I calculated it: ASUS’s firmware page for this model says it reached end of life and its firmware will no longer be updated, next to the final firmware 3.0.0.4.386_52334. ASUS gives no separate date, so we use that final firmware’s release date (2026-05-07).

Firmware newer than 3.0.0.4.386_51915
Source: asus.com (opens in a new tab) · checked November 13, 2026
Basis: The maker lists this model for the CVEs below but doesn't name the fixed firmware for it. The version comes from a CVE record by another organisation or from the maker's download page. Only the last affected firmware is named, so we assumed newer firmware has the fix.

Firmware 3.0.0.4.386_51925 or later
Source: asus.com (opens in a new tab) · checked November 13, 2026
Basis: The maker lists this model for the CVEs below but doesn't name the fixed firmware for it. The version comes from a CVE record by another organisation or from the maker's download page.
- CVE-2024-0401 NVD CVE-2024-0401 (opens in a new tab)
Firmware built or released on or after September 12, 2023
Source: asus.com (opens in a new tab) · checked November 13, 2026
Basis: The source gives a date instead of a firmware version, so we assumed this model's firmware from that date on has the fix.

Firmware 3.0.0.4.384.81992 or later
Source: asus.com (opens in a new tab) · checked November 13, 2026
Basis: The firmware we recorded for this model is on a different version line from the fixed firmware, so we assumed it has the fix because its number or date is later.
