You probably right.
Although I only changed freeradius binaries, I have installed multiple
different versions of openssl and:
3.0.25
sudo ldd /usr/sbin/freeradius
    [...]
        libcrypto.so.1.1 => /lib/x86_64-linux-gnu/libcrypto.so.1.1 (0x00007f63e4e00000)
        libssl.so.1.1 => /lib/x86_64-linux-gnu/libssl.so.1.1 (0x00007f63e51d7000)
[...]

3.2
sudo ldd /usr/sbin/freeradius
[...]
        libcrypto.so.3 => /lib/x86_64-linux-gnu/libcrypto.so.3 (0x00007f749c200000)
        libssl.so.3 => /lib/x86_64-linux-gnu/libssl.so.3 (0x00007f749c155000)
[...]
So probably ssl3 hadles this differently (And probably I have no chance
to debug it due to lack of knowledge :( )
