Fixes the following vulnerability:
- CVE-2026-4878:
A flaw was found in libcap. A local unprivileged user can exploit a
Time-of-check-to-time-of-use (TOCTOU) race condition in the
`cap_set_file()` function. This allows an attacker with write access
to a parent directory to redirect file capability updates to an
attacker-controlled file. By doing so, capabilities can be injected
into or stripped from unintended executables, leading to privilege
escalation.

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.
