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-2026-98394 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-2026-98394/ (Markdown: https://insights.sbomify.com/CVE-2026-98394/index.md)","id":"CVE-2026-98394","markdown":"https://insights.sbomify.com/CVE-2026-98394/index.md","name":"CVE-2026-98394","record":{"aliases":["AZL-108119","BELL-CVE-2026-98394","DEBIAN-CVE-2026-98394","GHSA-78rw-466c-3p7p","UBUNTU-CVE-2026-98394"],"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":"none","summary":"A local attacker can cause a busy-wait denial of service in the Linux kernel by triggering a specific condition in the af_unix socket implementation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\naf_unix: Return immediately when manage_oob() returns NULL for 0-length buffer.\n\nFahad Alharbi reported that recv(0, MSG_PEEK) triggers busy-wait\nin unix_stream_read_generic() if recv() is blocking and the last\nskb in the queue is MSG_OOB skb.\n\nIn such a situation, TCP returns 0 immediately regardless of\nblocking or non-blocking.\n\nLet's follow the behaviour.","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":"af_unix: Return immediately when manage_oob() returns NULL for 0-length buffer.","id":"CVE-2026-98394","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"powerpc/entry: Fix irq_soft_mask corruption on replayed interrupt exit","id":"CVE-2026-98395"},"packages":[],"prev":{"headline":"net: ipv4: Fix UDP length overflow with PMTU discover and big MTU","id":"CVE-2026-98393"},"products":["Linux"],"published":"2026-10-14","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":"2026-10-19","vendors":["Linux"]},"summary":"A local attacker can cause a busy-wait denial of service in the Linux kernel by triggering a specific condition in the af_unix socket implementation.","url":"https://insights.sbomify.com/CVE-2026-98394/"}
