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-2022-21505 in the wild and no public exploit code.\n\nAffected product: Oracle 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-2022-21505/ (Markdown: https://insights.sbomify.com/CVE-2022-21505/index.md)","id":"CVE-2022-21505","markdown":"https://insights.sbomify.com/CVE-2022-21505/index.md","name":"CVE-2022-21505","record":{"aliases":["DEBIAN-CVE-2022-21505","UBUNTU-CVE-2022-21505"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"Attackers with high privileges can bypass kernel lockdown via kexec when IMA appraisal is in log mode and Secure Boot is disabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"linux","vendor":"oracle"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"In the linux kernel, if IMA appraisal is used with the \"ima_appraise=log\" boot param, lockdown can be defeated with kexec on any machine when Secure Boot is disabled or unavailable.
