Fixes the following vulnerability:
- CVE-2026-55199:
libssh2 through 1.11.1, fixed in commit 1762685, contains a pre-
authentication denial of service vulnerability in the SSH_MSG_EXT_INFO
handler in src/packet.c that allows a malicious SSH server to cause a
client CPU exhaustion loop by sending a crafted extension count value.
A malicious server can set nr_extensions to 0xFFFFFFFF during key
exchange, causing the client to spin in a tight CPU loop for over 60
seconds because return values from _libssh2_get_string() are unchecked
and the session timeout does not apply to CPU-bound loops.

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
