Short explanation

CVE-2026-92446 in the Eclipse ThreadX - GUIX binary resource loader causes out-of-bounds reads because the loader lacks resource length information.

Why does it matter?

This vulnerability can lead to sensitive memory read issues that may compromise confidentiality and impact system availability.

Show the technical text from the sources

`gx_binres_theme_load()` and `gx_binres_font_load()` take the resource as a bare `GX_UBYTE *` with no length, and `GX_BINRES_DATA_INFO` has no field to carry one. Every read is therefore performed at an offset the file itself chose, against a buffer whose extent the loader does not know. A resource that declares more data than it contains is read past its end, and an offset stored in the file is turned into a pointer without being bounded. This is a distinct defect from GHSA-hgcj-22cg-4hfv, which was an underflowed glyph count. It needs no underflow and no wrapped multiply: a perfectly well-formed, narrow glyph range reaches it.
