The latest November Samsung firmware for a phone in front of me has android.uid.system signed by the compromised certificate with SHA256 fingerprint 34df0e7a9f1cf1892e45c056b4973cd81ccf148a4050d11aea4ac5a65f900a42. This certificate is provided by com.samsung.android.svcagent version 6.0.01.6 which is also signed with the same compromised 34df0e7a9f1cf1892e45c056b4973cd81ccf148a4050d11aea4ac5a65f900a42 certificate. The latest version of com.samsung.android.svcagent I could find is 7.0.00.1[1] which has a creation date of 2 September 2022 and also provides the compromised 34df0e7a9f1cf1892e45c056b4973cd81ccf148a4050d11aea4ac5a65f900a42 certificate.

On top of that, at least for the S21 series Samsung phones in their Common Criteria evaluated mode seemingly use the compromised 34df0e7a9f1cf1892e45c056b4973cd81ccf148a4050d11aea4ac5a65f900a42 certificate provided by earlier version 5.0.00.11 of com.samsung.android.svcagent[2]. I couldn't find a published applications list for S22 series phones in Common Criteria mode but suspect com.samsung.android.svcagent 7.0.00.1 from 2 September 2022 would be more recent anyway.
