CVE-2023-45955
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 · uneditedAn issue discovered in Nanoleaf Light strip v3.5.10 allows attackers to cause a denial of service via crafted write binding attribute commands.
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 confidenceA denial of service vulnerability exists in Nanoleaf Light Strip firmware v3.5.10 where the device fails to properly validate or handle specially crafted BLE GATT write binding attribute commands, causing the device to become unresponsive or crash.
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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Nanoleaf Light Strip modelIdentify if the device is a Nanoleaf Light Strip (flexible LED light strip product). Check the device packaging, purchase documentation, or the Nanoleaf app for model confirmation.Affected if Device is not a Nanoleaf Light Strip - this CVE only applies to this specific product.
-
Check firmware versionOpen the Nanoleaf mobile app, select the Light Strip device, and navigate to Device Settings > Firmware Version. Alternatively, check the device label or accompanying documentation.Affected if Firmware version is exactly 3.5.10 - this is the only affected version.
-
Verify BLE is enabledCheck if Bluetooth Low Energy pairing is active on the device. This can be done through the Nanoleaf app under device settings, or by observing if the device is in pairing mode (typically indicated by blinking LED patterns).Affected if BLE is enabled and the device is in pairing/discoverable mode - the vulnerability is exploitable via BLE GATT write commands.
-
Check device responsivenessAttempt to control the Light Strip through the Nanoleaf app (toggle power, change color, adjust brightness). Observe if commands execute normally or if the device becomes unresponsive.Affected if Device is unresponsive or crashes when receiving BLE GATT write commands, particularly binding-related commands - this indicates potential exploitation.
You are affected only if you have a Nanoleaf Light Strip running firmware version 3.5.10 with BLE enabled, as this CVE does not apply to any other versions or products.

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.
From vendor dataThe vendor must release a firmware patch that implements proper input validation on BLE GATT attribute write handlers, specifically for binding-related commands. Users should update to the patched firmware once available and avoid leaving BLE pairing enabled when not in use.
