It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47104 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- libusb (PyPI): affected all versions; fixed in 1.0.30\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-47104/ (Markdown: https://insights.sbomify.com/CVE-2026-47104/index.md)","id":"CVE-2026-47104","markdown":"https://insights.sbomify.com/CVE-2026-47104/index.md","name":"CVE-2026-47104","record":{"aliases":["AZL-88409","AZL-89156","BELL-CVE-2026-47104","DEBIAN-CVE-2026-47104","ECHO-a3a1-40f9-fc5f","GHSA-fh6g-r8pf-wqgw","JLSEC-2026-666","MINI-fg8v-hvj7-8fgp","PYSEC-2026-3979"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"USB library","requires_auth":"none","summary":"Attackers can cause a denial of service in applications using libusb by supplying malformed USB descriptors that trigger an out-of-bounds read.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"libusb","vendor":"libusb"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"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.
