Hello,

This is an announcement of TF-M v1.6.1 hotfix preparation. The reason for the hot fix is the recently found incorrect stack sealing in Library model.

The library mode is deprecated already but is available in v1.6.0 and the intention is to leave it in the best shape to our knowledge.

Security analysis shows no vulnerability was brought by this defect, so it is not a security fix.

The plan is to issue the fix by Nov 17.

TF-M release cadence and process is here: https://tf-m-user-guide.trustedfirmware.org/releases/release_process.htmlteam

Thanks,

Anton
