SUSE CVE-2026-91189

The GUIX binary resource loader never checks that a font page's glyph range is well formed. gxpageheaderfirstglyph and gxpageheaderlastglyph are read verbatim from the file and only the upper bound of lastglyph is validated, so a page declaring firstglyph lastglyph makes last - first + 1 underflo...

SUSE CVE-2026-92449

gxbinrespixelmaptableload in the GUIX binary resource theme loader indexes the pixelmap table with a value read verbatim from the resource file and never bounds it against the table size. A crafted theme drives a write of up to roughly 256 KB past the end of the table. The overflowed buffer is...

CVE-2026-91189 GUIX binary resource loader: unvalidated glyph range causes an integer underflow and a heap out-of-bounds write when loading an untrusted font or theme

The GUIX binary resource loader never checks that a font page's glyph range is well formed. gxpageheaderfirstglyph and gxpageheaderlastglyph are read verbatim from the file and only the upper bound of lastglyph is validated, so a page declaring firstglyph lastglyph makes last - first + 1 underflo...

CVE-2026-91189

The GUIX binary resource loader is vulnerable to a heap out-of-bounds write when processing untrusted fonts or themes. The root cause is an integer underflow occurring because the loader fails to verify that a font page's glyph range is well-formed; specifically, if first_glyph > last_glyph, t...

CVE-2026-91189

The GUIX binary resource loader never checks that a font page's glyph range is well formed. "gxpageheaderfirstglyph" and "gxpageheaderlastglyph" are read verbatim from the file and only the upper bound of "lastglyph" is validated, so a page declaring "firstglyph lastglyph" makes "last - first + 1...

CVE-2026-92446 GUIX binary resource loader reads past the end of a resource, because no length for it ever reaches the loader

gxbinresthemeload and gxbinresfontload take the resource as a bare GXUBYTE with no length, and GXBINRESDATAINFO 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 da...

CVE-2026-92446

The GUIX binary resource loader contains an out-of-bounds read vulnerability within the gx_binres_theme_load() and gx_binres_font_load() functions. The root cause is that these functions accept resources as a bare GX_UBYTE * without a length, and the GX_BINRES_DATA_INFO structure lacks a field to...

CVE-2026-92449 Binary resource loader: unbounded map_id from a theme file causes a heap out-of-bounds write in the GUIX-allocated arena

gxbinrespixelmaptableload in the GUIX binary resource theme loader indexes the pixelmap table with a value read verbatim from the resource file and never bounds it against the table size. A crafted theme drives a write of up to roughly 256 KB past the end of the table. The overflowed buffer is...

CVE-2026-92449

The GUIX binary resource (theme) loader contains a heap out-of-bounds write vulnerability in the _gx_binres_pixelmap_table_load() function. The root cause is the lack of bounds checking on the map_id value read directly from a resource file when indexing the pixelmap table . A crafted theme file ...
