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-2026-68424 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-68424/ (Markdown: https://insights.sbomify.com/CVE-2026-68424/index.md)","id":"CVE-2026-68424","markdown":"https://insights.sbomify.com/CVE-2026-68424/index.md","name":"CVE-2026-68424","record":{"aliases":["DEBIAN-CVE-2026-68424","GHSA-7mvh-m34r-f6vc","UBUNTU-CVE-2026-68424"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A use-after-free vulnerability in the Linux kernel's MTD virtual concatenation driver allows local attackers with high privileges to execute arbitrary code or escalate privileges.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy_joins()\n\nmtd_concat_destroy() frees item-\u003econcat so calling\nmtd_virt_concat_put_mtd_devices(item-\u003econcat) leads to a use after free.\n\nFix this by moving mtd_virt_concat_put_mtd_devices() before\nmtd_concat_destroy()","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":"mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy_joins()","id":"CVE-2026-68424","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"IB/mad: Drop unmatched RMPP responses before reassembly","id":"CVE-2026-68425"},"packages":[],"prev":{"headline":"mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy()","id":"CVE-2026-68423"},"products":["Linux"],"published":"2026-08-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-17","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel's MTD virtual concatenation driver allows local attackers with high privileges to execute arbitrary code or escalate privileges.","url":"https://insights.sbomify.com/CVE-2026-68424/"}
