It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version (see COPYING).\r\n\r\nSecurity Fix(es):\n\nlibusb 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-2026-23679)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"libusbx","purl":"pkg:rpm/openEuler/libusbx&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.26-3.oe2403sp3"}]}],"ecosystem_specific":{"aarch64":["libusbx-1.0.26-3.oe2403sp3.aarch64.rpm","libusbx-debuginfo-1.0.26-3.oe2403sp3.aarch64.rpm","libusbx-debugsource-1.0.26-3.oe2403sp3.aarch64.rpm","libusbx-devel-1.0.26-3.oe2403sp3.aarch64.rpm"],"src":["libusbx-1.0.26-3.oe2403sp3.src.rpm"],"x86_64":["libusbx-1.0.26-3.oe2403sp3.x86_64.rpm","libusbx-debuginfo-1.0.26-3.oe2403sp3.x86_64.rpm","libusbx-debugsource-1.0.26-3.oe2403sp3.x86_64.rpm","libusbx-devel-1.0.26-3.oe2403sp3.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2743"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23679"}],"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}],"database_specific":{"severity":"Medium"}}
