CVE-2025-49482
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.
NVD · uneditedImproper Resource Shutdown or Release vulnerability in ASR180x 、ASR190x in tr069 modules allows Resource Leak Exposure. This vulnerability is associated with program files tr069/tr098.c. This issue affects Falcon_Linux、Kestrel、Lapwing_Linux: before v1536.
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 · moderate confidenceImproper Resource Shutdown or Release vulnerability in the TR-069 (CWMP) module's tr098.c file allows resource leak exposure. This affects ASR180x and ASR190x hardware variants running Falcon_Linux, Kestrel, or Lapwing_Linux firmware versions prior to v1536, potentially leading to resource exhaustion over time.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify hardware variantDetermine if the device is an ASR180x or ASR190x variant. This is typically found in the system information, device specifications, or boot logs.Affected if The hardware is NOT an ASR180x or ASR190x variant, then the check does not apply.
-
Identify firmware typeDetermine the firmware distribution name. Check system files such as /etc/os-release, firmware banner, or boot logs for the OS name (Falcon_Linux, Kestrel, or Lapwing_Linux).Affected if The firmware is NOT one of Falcon_Linux, Kestrel, or Lapwing_Linux, then the check does not apply.
-
Check firmware versionRetrieve the installed firmware version. This is usually accessible via system information files, the web UI, CLI show commands, or boot logs. Compare the version number against 1536.Affected if The firmware version is less than 1536 (for example, v1500, v1520, or any build prior to v1536).
-
Verify TR-069/CWMP module is enabledCheck if the TR-069 (CWMP) service is configured and active. Inspect the configuration files for the tr098 module or the CWMP daemon, typically found in /etc/config/, /etc/tr069/, or similar configuration directories depending on the firmware build.Affected if TR-069 (CWMP) is enabled and the tr098 module is loaded or configured on the device.
A user is affected if they are running ASR180x or ASR190x hardware with Falcon_Linux, Kestrel, or Lapwing_Linux firmware prior to version 1536, and the TR-069/CWMP module with tr098.c is enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1536
Upgrade to firmware version v1536 or later which contains the proper resource cleanup fix for the tr098.c TR-069 module.
v1536 (or any version >= 1536)
- Upgrade Falcon Linux to version 1536 or later
- Upgrade Kestrel to version 1536 or later
- Upgrade Lapwing Linux to version 1536 or later
- Verify the upgrade by checking the version number post-upgrade
