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-2026-74679 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-74679/ (Markdown: https://insights.sbomify.com/CVE-2026-74679/index.md)","id":"CVE-2026-74679","markdown":"https://insights.sbomify.com/CVE-2026-74679/index.md","name":"CVE-2026-74679","record":{"aliases":["BELL-CVE-2026-74679","DEBIAN-CVE-2026-74679","GHSA-6qhg-x625-34c5","UBUNTU-CVE-2026-74679"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB gadget","requires_auth":"none","summary":"A malicious USB host can trigger an integer overflow in the Linux kernel NCM gadget driver, leading to an out-of-bounds memory read.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_ncm: Use unsigned int for ndp_index\n\nThe variable ndp_index is declared as a signed integer, but it stores\nthe return value of get_ncm(), which is unsigned.\n\nA malicious host can supply a large offset that overflows the signed\nndp_index, making it negative.
