mbed-os-5.15.9
We are pleased to announce the Mbed OS 5.15.9 release is now available.
Summary
We anticipate this release to be our final Mbed OS 5.15.x release as we have fulfilled our commitment of a two year support period for Mbed OS 5.15. We continue to focus our support efforts on Mbed 6 and encourage anyone who hasn’t yet migrated from Mbed 5.x.x to Mbed 6 to do so.
The contents of this release are predominantly defect fixes plus documentation changes to address a security vulnerability identified in the Mbed BLE implementation, which can be avoided by using full encryption instead of signed writes.
Migration Guide
This section lists specific changes which are part of this release and may
need special attention.
Bluetooth: Inform privacy risk of using signed writes.
Summary of changes
The Cordio stack uses a single CSRK. It can be used by a
malicious device to track the Mbed OS application if signed
writes are used.
This PR documents the issue and explain workaround an application can
adopt.
GitHub actions: Update checkout version and use safe.directory
Summary of changes
GitHub actions is failing due to not finding directories. This change fixes this by upgrading the checkout to v3 and using
