It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-74585 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-2026-74585/ (Markdown: https://insights.sbomify.com/CVE-2026-74585/index.md)","id":"CVE-2026-74585","markdown":"https://insights.sbomify.com/CVE-2026-74585/index.md","name":"CVE-2026-74585","record":{"aliases":["BELL-CVE-2026-74585","DEBIAN-CVE-2026-74585","GHSA-2wmm-p327-9hx6","UBUNTU-CVE-2026-74585"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A malicious Thunderbolt device can trigger an out-of-bounds write in the Linux kernel, potentially leading to code execution or privilege escalation.","user_interaction":"required","vuln_class":"memory_corruption"},"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\nthunderbolt: Bound the DROM dual link port number before indexing sw-\u003eports\n\ntb_drom_parse_entry_port() validates the device-supplied header-\u003eindex\nagainst sw-\u003econfig.max_port_number before indexing sw-\u003eports[], but the\nsibling field entry-\u003edual_link_port_nr -- a 6-bit value also read from\nthe DROM -- indexes the same array with no such check.
