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-2026-88839 in the wild and no public exploit code.\n\nAffected product: Red Hat Hardened Images. 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-2026-88839/ (Markdown: https://insights.sbomify.com/CVE-2026-88839/index.md)","id":"CVE-2026-88839","markdown":"https://insights.sbomify.com/CVE-2026-88839/index.md","name":"CVE-2026-88839","record":{"aliases":["AZL-105125","DEBIAN-CVE-2026-88839","ECHO-2dbb-f14e-a8c4","GHSA-fr4j-cp66-9wc4","UBUNTU-CVE-2026-88839"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"BusyBox utility","requires_auth":"high_privilege","summary":"An out-of-bounds write in BusyBox's passwd/group parser allows attackers to corrupt memory, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"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-787","name":"Out-of-bounds Write"}],"description":"BusyBox passwd/group tokenize() references a stale endpoint pointer after trimming, causing an out-of-bounds write of heap pointers.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Busybox: busybox: passwd/group parser writes heap pointers out of bounds due to stale tokenize() endpoint","id":"CVE-2026-88839","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Busybox: busybox: tls ssl_server reads one byte out of bounds when parsing truncated clienthello","id":"CVE-2026-88840"},"packages":[],"prev":{"headline":"Busybox: busybox: non-root mount option filter bypass allows clearing fstab security restrictions","id":"CVE-2026-88838"},"products":["Red Hat Hardened Images"],"published":"2026-09-23","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-25","vendors":["Red Hat"]},"summary":"An out-of-bounds write in BusyBox's passwd/group parser allows attackers to corrupt memory, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-88839/"}
