CVE-2026-1837 (GCVE-0-2026-1837)

Title
libjxl: Out-of-bounds write in grayscale color transformation when using LCMS2
Summary
A specially-crafted file can cause libjxl's decoder to write pixel data to uninitialized unallocated memory. Soon after that data from another uninitialized unallocated region is copied to pixel data.
This can be done by requesting color transformation of grayscale images to another grayscale color space. Buffers allocated for 1-float-per-pixel are used as if they are allocated for 3-float-per-pixel. That happens only if LCMS2 is used as CMS engine. There is another CMS engine available (selected by build flags).

libjxl: Uninitialized memory read in decoder due to incorrect optimization in patch handling
Summary
A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory.
This can be done by causing the decoder to reference an outside-image-bound area in a subsequent patches. An incorrect optimization causes the decoder to omit populating those areas.

CVE-2026-1837 (GCVE-0-2026-1837)

Title
libjxl: Out-of-bounds write in grayscale color transformation when using LCMS2
Summary
A specially-crafted file can cause libjxl's decoder to write pixel data to uninitialized unallocated memory. Soon after that data from another uninitialized unallocated region is copied to pixel data.
This can be done by requesting color transformation of grayscale images to another grayscale color space. Buffers allocated for 1-float-per-pixel are used as if they are allocated for 3-float-per-pixel. That happens only if LCMS2 is used as CMS engine. There is another CMS engine available (selected by build flags).
