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 · unedited
An unauthenticated  denial of service vulnerability exists in the SMM v1, SMM v2, and FPC management web server which can be triggered under crafted conditions. Rebooting SMM or FPC will restore access to the management web server.

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 confidence

An unauthenticated denial of service vulnerability affects the SMM v1, SMM v2, and FPC management web servers. By sending specially crafted requests under specific conditions, an attacker can cause the management web server to become unresponsive, requiring a reboot of the SMM or FPC module to restore access.

MitigationApply vendor-provided patches or firmware updates for SMM and FPC modules. If patches are unavailable, consider network segmentation to restrict access to management interfaces and implement rate limiting or firewall rules to mitigate malformed request attacks.

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 the enclosure product model
    Access the system management interface or use IPMI/Redfish to query the enclosure or SMM module model information. Look for model identifiers such as N1200, Thinkagile Cp Cb 10, Thinkagile Hx, Thinkagile Vx, Thinksystem D2, Thinksystem Da240, or Thinksystem Dw612.
    Affected if The product model matches any of the following: Lenovo Nextscale N1200, Thinkagile Cp Cb 10/10e, Thinkagile Hx, Thinkagile Vx, Thinksystem D2, Thinksystem Da240, or Thinksystem Dw612 enclosures.
  2. Check the SMM or FPC firmware version
    Use the enclosure's web management interface, IPMI, or Redfish API to query the SMM (System Management Module) or FPC (Fabric Pass-Through Controller) firmware version. The version string typically appears in the firmware or module information section.
    Affected if The firmware version is lower than fhet60b-3.40 (for N1200), lower than tesm38c-1.26 (for Thinkagile Cp Cb 10/10e, Hx, Vx, and Thinksystem D2), or lower than umsm10s-1.07 (for Thinksystem Da240 and Dw612).
  3. Verify the management web server is accessible
    Attempt to access the SMM or FPC web management interface via HTTPS/HTTP on the management network. Check if the web interface responds to requests on the typical management ports (typically 443 or 8443 for HTTPS).
    Affected if The SMM v1, SMM v2, or FPC management web server is reachable over the network and responds to HTTP/HTTPS requests.
  4. Confirm the web server type is SMM or FPC
    Examine the management interface banner, login page, or API responses to identify if the management web server is specifically an SMM v1, SMM v2, or FPC module web interface. This may be visible in the HTML title, favicon, or welcome message.
    Affected if The management web server is identified as an SMM v1, SMM v2, or FPC management interface.

You are affected if your enclosure matches one of the listed product models AND your firmware version is below the specified threshold AND the SMM or FPC management web server is accessible on your network.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor-provided patches or firmware updates for SMM and FPC modules. If patches are unavailable, consider network segmentation to restrict access to management interfaces and implement rate limiting or firewall rules to mitigate malformed request attacks.

Recommended fix High confidence

fhet60b-3.40 (Nextscale N1200), tesm38c-1.26 (Thinkagile Cp Cb 10/10e, Thinkagile Hx, Thinkagile Vx, Thinksystem D2), or umsm10s-1.07 (Thinksystem Da240, Thinksystem Dw612)

  1. 1. Identify the specific Lenovo enclosure or node model from the affected product list
  2. 2. Navigate to Lenovo support portal (support.lenovo.com) and locate the firmware download page for your specific model
  3. 3. Download the appropriate fixed firmware version based on your model: For Nextscale N1200 use fhet60b-3.40 or later, for Thinkagile Cp Cb 10/10e, Thinkagile Hx, Thinkagile Vx, or Thinksystem D2 use tesm38c-1.26 or later, for Thinksystem Da240 or Dw612 use umsm10s-1.07 or later
  4. 4. Follow Lenovo's standard firmware update procedure for the enclosure/node (typically via BMC/IMM web interface or Lenovo XClarity Administrator)
  5. 5. After firmware update, verify the SMM or FPC management web server is accessible
  6. 6. If the web server becomes unresponsive post-update, reboot the SMM or FPC component to restore access as a fallback
