As a quick hack, you could try the attached patch against libosmocore.

This is just a hack to see if we really have found the culprit. It would only work if no other part of the communication uses the UICC F2 instruction at another time. It's far from a proper solution, but worth a try.

I've meanwile figured out that the upper 4 bits of the P1 octet are guaranteed to be different in the ETSI UICC vs. GlobalPlatform F2 command. So we can use those as an indicator to distinguish the two situations. See the [still untested] patch at https://gerrit.osmocom.org/c/libosmocore/+/36501

Feel free to give that one a try and let us know if that helps.

Thanks, Harald
