An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-74238 in the wild and no public exploit code.\n\nAffected product: tier4 nebula. 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-2026-74238/ (Markdown: https://insights.sbomify.com/CVE-2026-74238/index.md)","id":"CVE-2026-74238","markdown":"https://insights.sbomify.com/CVE-2026-74238/index.md","name":"CVE-2026-74238","record":{"aliases":["GHSA-77m7-4hpw-56g7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Autonomous driving sensor library","requires_auth":"none","summary":"Unauthenticated remote attackers can trigger heap out-of-bounds reads in the VLP32 UDP decoder, leaking memory or causing crashes in autonomous driving systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"TIER IV Nebula through 1.2.0 contains an out-of-bounds read vulnerability in the Vlp32Decoder::unpack() function that allows unauthenticated remote attackers to cause the decoder to read past the end of a received UDP buffer into adjacent heap memory by sending a short UDP datagram.
