For change log, see: https://github.com/mguentner/cannelloni/releases/tag/v2.0.1 https://github.com/mguentner/cannelloni/releases/tag/v2.1.0 https://github.com/mguentner/cannelloni/releases/tag/v2.1.1 https://github.com/mguentner/cannelloni/releases/tag/v2.1.2 2.1.2 fixes CVE-2026-37539 (CVSS 3.1 score 9.8, CWE-121): a stack based buffer overflow in CAN frame parsing, in parseCANFrame() in parser.cpp and decodeFrame() in decoder.cpp, allowing remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted CAN FD frames. The advisory names v2.0.0 explicitly, so the version used so far is affected. The CVE is not reported by https://security.buildroot.org/master/component/cannelloni because its NVD entry has no CPE data (vendor and product are both "n/a") and can therefore not be matched against the package version. Apart from the security fix, 2.0.0..2.1.2 contains only a handful of changes: undeliverable frames are dropped after a timeout on a broken CAN bus, variable length arrays are gone, the default remote address is fixed, and pthreads are looked up with the CMake module instead of by hand. 2.1.1 is a maintenance release only, as the 2.1.0 tag pointed to a commit that was not the final one.

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.
