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-2026-98751 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-2026-98751/ (Markdown: https://insights.sbomify.com/CVE-2026-98751/index.md)","id":"CVE-2026-98751","markdown":"https://insights.sbomify.com/CVE-2026-98751/index.md","name":"CVE-2026-98751","record":{"aliases":["AZL-108975","BELL-CVE-2026-98751","DEBIAN-CVE-2026-98751","GHSA-cg92-2wfv-ppg3","UBUNTU-CVE-2026-98751"],"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 race condition in Linux kernel TTY break signaling allows local attackers to trigger a denial of service by racing hangup with break ioctls.","user_interaction":"not_required","vuln_class":"race_condition"},"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\ntty: abort break signalling on hangup\n\nThe break ioctls can race with hangup and end up calling into a tty\ndriver for a device that is already gone or powered down.\n\nDrivers must handle this race, but TCSBRK and TCSBRKP should still be\naborted to avoid calling back into the driver after a user-controlled\ntimeout (possibly even after the tty has been reopened).\n\nNote that drivers should disable any break state on shutdown so just\nreturn on hangup (calling break_ctl() again is racy and will most likely\nfail for drivers handling the race).","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":"tty: abort break signalling on hangup","id":"CVE-2026-98751","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"tty: port: fix tty_port_tty_vhangup() race","id":"CVE-2026-98752"},"packages":[],"prev":{"headline":"tty: fix saved termios reset race","id":"CVE-2026-98750"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-21","vendors":["Linux"]},"summary":"A race condition in Linux kernel TTY break signaling allows local attackers to trigger a denial of service by racing hangup with break ioctls.","url":"https://insights.sbomify.com/CVE-2026-98751/"}
