It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-26158 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 6. 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-2026-26158/ (Markdown: https://insights.sbomify.com/CVE-2026-26158/index.md)","id":"CVE-2026-26158","markdown":"https://insights.sbomify.com/CVE-2026-26158/index.md","name":"CVE-2026-26158","record":{"aliases":["AZL-77606","AZL-77613","BELL-CVE-2026-26158","DEBIAN-CVE-2026-26158","ECHO-473c-40b9-e821","GHSA-r8f8-4pgh-4m8v","UBUNTU-CVE-2026-26158","openSUSE-SU-2026:10231-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"BusyBox utility","requires_auth":"none","summary":"Attackers can modify arbitrary files and escalate privileges by extracting malicious tar archives with unvalidated hardlink or symlink entries in BusyBox.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"A flaw was found in BusyBox.
