Fixes the following CVEs:
(CVE numbers will be added when assigned.)
CVE-2026-XXXXX (GHSA-x8r2-mggj-j6wr) Heap buffer overflow (write) in the
uncompressed (unci) mixed-interleave decoder when the two chroma
components declare different bit depths. Both the written bytes and the
overflow length are controlled by the file. (critical)
CVE-2026-XXXXX (GHSA-8fmq-r4pf-7m57) Permanent decoder deadlock through
a reference cycle between an image and its alpha auxiliary image. The
alpha edge was not covered by the cycle guard and re-entered a held
mutex. (high)
CVE-2026-XXXXX (GHSA-w7mc-p8jc-p853) Heap out-of-bounds read in the
YCbCr 4:2:0 to 16-bit interleaved RGB conversion when the chroma
planes have a lower bit depth than luma. Heap memory could end up in
the decoded image. YCbCr conversions with mismatched luma and chroma
bit depths are now rejected. (high)
CVE-2026-XXXXX (GHSA-4jqm-2x34-6f6r) Heap buffer overflow in the SVT-AV1
encoder plugin when encoding a high-bit-depth alpha channel, and a
double free on its send-picture error path. (high)
CVE-2026-84451 (GHSA-hh47-fhqr-cj2r) Incomplete fix for
GHSA-73p7-m7gg-w2jv: the tile range check of the unci decoder (without
icef) could still overflow, allowing an out-of-bounds read. (medium)
CVE-2026-XXXXX (GHSA-4h82-g446-83fm) Heap out-of-bounds read when
converting odd-height 4:2:0 frames of an uncompressed (uncv) image
sequence to RGB. (medium)
CVE-2026-XXXXX (GHSA-9rj8-5mp5-26c9) Out-of-bounds read in the RGB to
YCbCr identity-matrix color conversion when the R, G, and B planes
have different bit depths. (medium)
CVE-2026-84450 (GHSA-gh5q-69gg-c964) A clap property combined with an
oversized ispe reached an assert() in the Fraction arithmetic and
aborted the process (incomplete fix for GHSA-jc8f-p23p-5hjg). An error
is returned instead. (medium)
(GHSA-mw6f-29j3-76f4) Several smaller findings:
heif_image_handle_get_depth_image_handle() and
heif_image_handle_get_depth_image_representation_info() dereferenced a
null pointer on files without a depth image; the TIFF input decoder of
the example tools had an unbounded EXIF tag allocation and a division
by zero on zero YCbCr subsampling; assert()s in the PNG input decoder
are now error returns; integer overflow in the Go binding's
ImageAccess.GetPlane(); heif-view now verifies the decoded frame size
before display. (medium)
(GHSA-8857-r8x5-7499) Undefined behavior (negative shift) in the HDR
bit-depth up-conversion for target bit depths above 16. Such
conversions are now rejected. (low)

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
