You probably didn't set your the writable flag for the program section
that includes .data. If you created your program section header table
manually, make sure that p_flags (the second-to-last field) includes
the writable flag (4 = readable, 2 = writable, 1 = executable).

No, the section header table is not used when loading/executing ELF
binaries.
