Buildroot LTS 2025.02.x utilises libglib2 version 2.82.5 which is prone to CVE-2025-6052 [1]. 0001-gstring-Fix-overflow-check-when-expanding-the-string.patch is included in the package/libglib2 directory. This patch mitigates CVE-2025-6052 as seen in [1], by backporting to libglib2 2.82.5. libglib2 shares part of its infrastructure with libglib2-bootstrap, by adding the patch in package/libglib2 the patch isn't applied to libglib2-bootstrap. When building libglib2, the patch was correctly applied in output/build/host-libglib2-2.82.5/glib/gstring.c . When building libglib2-bootstrap it was verified that the patch was not applied here.

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 http://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.
