How to Read Ledger Security Bulletins — CVE, Patch, Affected Models

Security bulletins are short but dense. A three-column mental model gets you 90% of what you need.

1. The CVE

Common Vulnerabilities and Exposures number — lets you cross-reference the issue with third-party analysis.

2. The patch

Firmware version that fixes the issue. Install the matching version or newer.

3. Affected models

Not every bulletin affects every model. Confirm your model is in the list before panicking — and confirm it's not in the list before assuming you're safe.

Ranking urgency

Remote attacks without user interaction — highest urgency. Local attacks requiring physical access — medium. Theoretical issues with no known exploit — low.

Safety reminder: Use only the official Ledger site and Ledger Live. Never type your recovery phrase or PIN into a webpage and never share them with anyone. Pause and verify the moment anything looks unusual.
