examples/fips_validation: fix null dereferences
One issue caught by Coverity 343408 *deref_parm: Directly dereferencing parameter val->val. In writeback_tdes_hex_str(), tmp_val is initialised to null. tmp_val.val is updated only if keys are found. If keys are not found,it doesn't fails but continues to invoke writeback_hex_str(),where val->val is accessed without null check. The fix is to return the error, if keys are not found in writeback_tdes_hex_str(). Coverity issue: 343408 Fixes: 527cbf3d5e ("examples/fips_validation: support TDES parsing") Cc: Signed-off-by: Chaitanya Babu Talluri <> Acked-by: Akhil Goyal <>
