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-2026-124743 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\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-2026-124743/ (Markdown: https://insights.sbomify.com/CVE-2026-124743/index.md)","id":"CVE-2026-124743","markdown":"https://insights.sbomify.com/CVE-2026-124743/index.md","name":"CVE-2026-124743","record":{"aliases":["GHSA-gjcv-9jxm-vqjv","UBUNTU-CVE-2026-124743"],"analysis":{"component_type":"operating_system","exploitable_when_present":false,"fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"embedded Unix utilities","requires_auth":"none","requires_specific_call":false,"summary":"A crafted HFS+ filesystem image can crash BusyBox via divide-by-zero, preventing device resolution; Linux systems mounting untrusted media should care.","user_interaction":"required","vuln_class":"denial_of_service","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"redhat","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-369","name":"Divide By Zero"}],"description":"A flaw was found in BusyBox.
