{"id":"JLSEC-2026-665","summary":"libusb before version 1.0.30 contains a NULL pointer dereference vulnerability that allows attackers...","details":"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.","modified":"2026-07-25T18:24:45.251446902Z","published":"2026-07-14T14:59:33.004Z","upstream":["CVE-2026-23679","GHSA-jp69-qvgm-mqwx","EUVD-2026-32502"],"database_specific":{"license":"CC-BY-4.0","sources":[{"modified":"2026-07-14T16:16:52.027Z","published":"2026-05-27T14:16:44.170Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-23679","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23679","database_specific":{"status":"Modified"},"id":"CVE-2026-23679","imported":"2026-07-17T22:22:04.035Z"},{"url":"https://api.github.com/advisories/GHSA-jp69-qvgm-mqwx","html_url":"https://github.com/advisories/GHSA-jp69-qvgm-mqwx","id":"GHSA-jp69-qvgm-mqwx","imported":"2026-07-17T22:22:04.198Z","modified":"2026-05-27T15:33:19Z","published":"2026-05-27T15:33:11Z"},{"id":"EUVD-2026-32502","imported":"2026-07-17T22:22:14.114Z","modified":"2026-07-14T15:53:32Z","published":"2026-05-27T13:21:37Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-32502","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-32502"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-jp69-qvgm-mqwx"},{"type":"WEB","url":"https://github.com/libusb/libusb/commit/578ab76b4c434f8b204137ab6d7310689c7a9704"},{"type":"WEB","url":"https://github.com/libusb/libusb/issues/1813"},{"type":"WEB","url":"https://github.com/libusb/libusb/pull/1814"},{"type":"WEB","url":"https://github.com/libusb/libusb/releases/tag/v1.0.30"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23679"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/libusb-null-pointer-dereference-in-parse-interface"}],"affected":[{"package":{"name":"libusb_jll","ecosystem":"Julia","purl":"pkg:julia/libusb_jll?uuid=a877fdc9-fe69-5ed6-b93d-11ecd0dc2d49"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.0.30+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-665.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
