package/libusb: security bump to version 1.0.30

Browse Source 
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.
