CVE: CVE-2026-5928 (high) - libio: Fix ungetwc operating on byte stream [BZ #33998]. When _IO_wdefault_pbackfail attempts to push back one character, it accidentally compares the wchar to push back with the last char from byte stream, instead of wide stream. Under specific coding, attacker may exploit this to leak information.
