Root code execution via unbounded vCard copy
Published Aug 1, 2025 · Updated Aug 1, 2025
Stack-based buffer overflow in Alpine iLX-507 6.0.000 allows physically proximate attackers to execute code through malicious Bluetooth vCard data. The vCard parser copies user-supplied data into a fixed-length stack buffer without first validating its size against the destination. Exploitation requires the receiver to connect to a malicious Bluetooth device and yields arbitrary code execution as root.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
