Fixes the following security issues:
CVE-2026-23679: libusb before version 1.0.30 contains a NULL pointer
dereference vulnerability that allows attackers to crash applications by
supplying a malformed USB configuration descriptor where an interface claims
bNumEndpoints greater than zero but is followed by a class-specific
descriptor whose bLength exceeds the remaining buffer size, causing
parse_interface() to return early without allocating the endpoint array.
Attackers can exploit this flaw through libusb_get_active_config_descriptor
or libusb_get_config_descriptor by providing crafted descriptors via
virtualized USB passthrough, file-based descriptor parsing, or network
sources, causing any application iterating over endpoints to dereference a
NULL endpoint pointer and crash.

CVE-2026-47104: libusb before version 1.0.30 contains a one-byte
out-of-bounds read vulnerability in parse_iad_array() in descriptor.c that
allows attackers to trigger a denial of service by supplying a malformed USB
descriptor whose bLength equals size minus one, causing the bounds check to
use the original buffer size instead of the remaining size. Attackers in
virtualized environments with USB passthrough can supply crafted descriptors
through libusb_get_active_interface_association_descriptors or
libusb_get_interface_association_descriptors to read one byte past the end
of the malloc allocation, resulting in a denial of service.

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
