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-2021-29795 in the wild and no public exploit code.\n\nAffected product: IBM PowerVM Hypervisor. 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-2021-29795/ (Markdown: https://insights.sbomify.com/CVE-2021-29795/index.md)","id":"CVE-2021-29795","markdown":"https://insights.sbomify.com/CVE-2021-29795/index.md","name":"CVE-2021-29795","record":{"aliases":["GHSA-jc84-3h2h-pgxj"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM PowerVM Hypervisor","requires_auth":"high_privilege","summary":"A local user can crash the IBM PowerVM Hypervisor system by sending a specially crafted sequence of hypervisor calls from a partition.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"powervm_hypervisor","vendor":"ibm"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:3.0/PR:H/S:C/AV:L/A:H/C:N/UI:N/AC:L/I:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"IBM PowerVM Hypervisor FW860, FW930, FW940, and FW950 could allow a local user to create a specially crafted sequence of hypervisor calls from a partition that could crash the system.
