Not looking at the implementation but sounds like an issue of Linux side to me. The error message seems intentional.
----------------------------------------
Bug #18881: IO#read_nonblock raises IOError when called following buffered character IO
https://bugs.ruby-lang.org/issues/18881#change-98202
* Author: javanthropus (Jeremy Bopp)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x64-mingw-ucrt]
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The following example code works as expected on Linux but raises an `IOError` on Windows:
``` ruby
r, w = IO.pipe
w.write("foobar")
c = r.getc
r.ungetc(c)
r.read_nonblock(3)
```
The error message is:
```
IOError: byte oriented read for character buffered IO
```
