Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-29647 exists.\n\nAffected product: n/a. 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-2026-29647/ (Markdown: https://insights.sbomify.com/CVE-2026-29647/index.md)","id":"CVE-2026-29647","markdown":"https://insights.sbomify.com/CVE-2026-29647/index.md","name":"CVE-2026-29647","record":{"aliases":["GHSA-8w4w-q822-g7ph"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"RISC-V simulator","requires_auth":"low_privilege","summary":"Lower-privileged code can access IMSIC state via CSRs despite permission restrictions, enabling information leakage or interrupt handling disruption in OpenXiangShan NEMU.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"In OpenXiangShan NEMU, insufficient Smstateen permission enforcement allows lower-privileged code to access IMSIC state via stopei/vstopei CSRs even when mstateen0.IMSIC is cleared, potentially enabling cross-context information leakage or disruption of interrupt handling.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Missing authorization in n/a","id":"CVE-2026-29647","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2026-29648"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2026-29646"},"products":["n/a"],"published":"2026-04-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-21","vendors":["n/a"]},"summary":"Lower-privileged code can access IMSIC state via CSRs despite permission restrictions, enabling information leakage or interrupt handling disruption in OpenXiangShan NEMU.","url":"https://insights.sbomify.com/CVE-2026-29647/"}
