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-2026-58088 in the wild and no public exploit code.\n\nAffected product: Freebsd Freebsd. 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-2026-58088/ (Markdown: https://insights.sbomify.com/CVE-2026-58088/index.md)","id":"CVE-2026-58088","markdown":"https://insights.sbomify.com/CVE-2026-58088/index.md","name":"CVE-2026-58088","record":{"aliases":["GHSA-7h55-5jqw-fvcq"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FreeBSD kernel","requires_auth":"none","summary":"A race condition in FreeBSD's ELF core dump allows local attackers to trigger a kernel heap overflow, potentially leading to privilege escalation.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"cvss":{"score":7.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them.
