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-2026-94370 in the wild and no public exploit code.\n\nAffected product: Qt_for_MCUs. 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-2026-94370/ (Markdown: https://insights.sbomify.com/CVE-2026-94370/index.md)","id":"CVE-2026-94370","markdown":"https://insights.sbomify.com/CVE-2026-94370/index.md","name":"CVE-2026-94370","record":{"aliases":["GHSA-vcv3-3vwp-2j63"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Qt for MCUs","requires_auth":"none","summary":"A double free or use-after-free in Qt for MCUs string handling allows attackers to cause memory corruption, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Qt","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:H/E:U/S:P/AU:N/R:U/V:D/RE:M","version":"4.0"},"cwes":[{"id":"CWE-665","name":"Improper Initialization"},{"id":"CWE-590","name":"Free of Memory not on the Heap"},{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-415","name":"Double Free"}],"description":"A defect in the Qt for MCUs core string handling causes heap memory corruption.
