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-2026-92454

The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating...

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...

CVE-2026-91059

The GUIX JPEG software decoder enforces no ordering on JPEG markers. A file that places a second SOF0 frame header after SOS re-runs the frame header parser after the output buffer has already been allocated and its geometry latched. The decoder returns GXSUCCESS and publishes a GXPIXELMAP whose...

CVE-2026-92454

The GUIX software JPEG decoder is vulnerable to an out-of-bounds read and a non-terminating loop when GX_SOFTWARE_DECODER_SUPPORT is enabled. The decoder fails to verify that four kinds of marker segments are long enough, causing truncated segments to be read past the end of the caller's image bu...

EUVD-2026-105046

The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating...

CVE-2026-92454 JPEG decoder: truncated segments are read past the image buffer, and a zero sampling factor hangs the decode

The GUIX software JPEG decoder reads four kinds of marker segment without checking that each is long enough to hold what it reads. A truncated segment is therefore read past the end of the caller's image buffer. Separately, a zero chroma sampling factor makes the block decode loop non-terminating...

EUVD-2026-105042

The GUIX JPEG software decoder enforces no ordering on JPEG markers. A file that places a second SOF0 frame header after SOS re-runs the frame header parser after the output buffer has already been allocated and its geometry latched. The decoder returns GXSUCCESS and publishes a GXPIXELMAP whose...

CVE-2026-91059 JPEG decoder: a duplicate SOF0 after SOS publishes a pixelmap that misreports its own allocation size

The GUIX JPEG software decoder enforces no ordering on JPEG markers. A file that places a second SOF0 frame header after SOS re-runs the frame header parser after the output buffer has already been allocated and its geometry latched. The decoder returns GXSUCCESS and publishes a GXPIXELMAP whose...

CVE-2026-91059

The GUIX JPEG software decoder is vulnerable to an out-of-bounds read (CWE-125) because it does not enforce ordering on JPEG markers. A crafted file containing a second SOF0 frame header after an SOS marker causes the decoder to re-run the frame header parser after the output buffer is already al...

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...

EUVD-2026-105040

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 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-2026-92446 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

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 ...

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...

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-2026-103414

The GUIX binary resource theme loader sizes its arena and populates it in two separate passes that traverse the resource file with independent cursor arithmetic. Because gxpageheaderdatasize is never validated against the glyph data a page actually contains, the two passes can read different page...
