Im also having this issue with sedutil-cli 1.49.4 version on Arch Linux and Samsung 990 Pro ssd

sedutil-cli: linux/DtaLinux.cpp:219: virtual DtaOS::dictionary* DtaLinux::getOSSpecificInformation(OSDEVICEHANDLE, const char*, unsigned char (&)[28], DTA_DEVICE_INFO&): Assertion `str_WWN.length()==(2*sizeof(device_info.worldWideName))' failed.

Looks like you hit a glitch in the develop branch code. Looks like this code is trying to look up eui 002538b431a18275 in the OUI database and not finding it. A possible sort of fix would be to updated the OUI database, but the correct fix is to allow the code to handle this problem, or whatever it is that is resulting in a computed WWN of "5" instead of a correct or acceptably-synthesized one. I'll make that a point to fix. Thanks for helping me test out code under development. As always, ymmv.
