This fixes the following vulnerabilities:
- CVE-2026-29111 (fixed in 258.5):
systemd, a system and service manager, (as PID 1) hits an assert and
freezes execution when an unprivileged IPC API call is made with
spurious data. On version v249 and older the effect is not an assert,
but stack overwriting, with the attacker controlled content. From
version v250 and newer this is not possible as the safety check causes
an assert instead. This IPC call was added in v239, so versions older
than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11
contain patches. No known workarounds are available.

- CVE-2026-40226 (fixed in 258.6):
In nspawn in systemd 233 through 259 before 260, an escape-to-host
action can occur via a crafted optional config file.

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.
