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-2026-72401 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-2026-72401/ (Markdown: https://insights.sbomify.com/CVE-2026-72401/index.md)","id":"CVE-2026-72401","markdown":"https://insights.sbomify.com/CVE-2026-72401/index.md","name":"CVE-2026-72401","record":{"aliases":["DEBIAN-CVE-2026-72401","GHSA-f5wx-qgf8-mmv9","UBUNTU-CVE-2026-72401"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel BPF verifier allows local attackers to cause denial of service by exhausting kernel memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nbpf: Fix insn_aux_data leak on verifier err_free_env path\n\nWhen bpf_check() allocates env-\u003einsn_aux_data successfully but later\nfails to allocate env-\u003esucc, it jumps directly to err_free_env.\n\nThe existing vfree(env-\u003einsn_aux_data) sits before the err_free_env\nlabel, so that direct jump bypasses it and leaks insn_aux_data.\n\nMove vfree(env-\u003einsn_aux_data) into err_free_env so all early and late\nexit paths release it consistently.","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":"bpf: Fix insn_aux_data leak on verifier err_free_env path","id":"CVE-2026-72401","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"bpf: Mask pseudo pointer values in verifier logs","id":"CVE-2026-72402"},"packages":[],"prev":{"headline":"seg6: validate SRH length before reading fixed fields","id":"CVE-2026-72400"},"products":["Linux"],"published":"2026-08-15","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 memory leak in the Linux kernel BPF verifier allows local attackers to cause denial of service by exhausting kernel memory.","url":"https://insights.sbomify.com/CVE-2026-72401/"}
