@darksapien23151 Thank you for the contribution!

Also could you tell me please if you launched tests using ./bin/[platform]/[build_type]/ov_cpu_func_tests --gtest_filter="*smoke*Eltwise*SqDiff*"?
I'd expect that some tests are failed now with exception unexpected primitive type.

Please check second part about tests in the paragraph What needs to be done? in the issue #27502.

Thank you for your feedback!

I have added the SQUARED_DIFF operation, following the required changes, and instantiated the tests for both static and dynamic shapes.

I will proceed with the second part mentioned in the issue #27502, specifically addressing the primitive type registration and ensuring that the SQUARED_DIFF operation works correctly in the test pipeline. I will debug and resolve the failure and update you once this is fixed.
