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-2026-98695 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-2026-98695/ (Markdown: https://insights.sbomify.com/CVE-2026-98695/index.md)","id":"CVE-2026-98695","markdown":"https://insights.sbomify.com/CVE-2026-98695/index.md","name":"CVE-2026-98695","record":{"aliases":["AZL-109016","BELL-CVE-2026-98695","DEBIAN-CVE-2026-98695","GHSA-w8fg-4vmm-x6q5","UBUNTU-CVE-2026-98695"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB serial","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel USB serial driver allows local attackers to cause a denial of service via NULL pointer dereference during device disconnection.","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\nUSB: serial: fix ioctl hangup race\n\nThe tty ioctls can race with hangup and end up calling into a tty driver\nfor a device that is already gone or powered down.\n\nSerialise the callbacks using the tty port mutex and add the missing\nchecks to make sure the port has not been hung up before accessing port\ndriver data or hardware.\n\nThis specifically avoids dereferencing a NULL-pointer if a device is\ndisconnected during lengthy break signalling.\n\nNote that TIOCGICOUNT and TIOCMIWAIT do not access port driver data or\nhardware and are therefore not affected by 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":"USB: serial: fix ioctl hangup race","id":"CVE-2026-98695","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":"USB: serial: fix driver deregistration order","id":"CVE-2026-98696"},"packages":[],"prev":{"headline":"thunderbolt: Fix KASAN reported use-after-free when request is canceled","id":"CVE-2026-98694"},"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 the Linux kernel USB serial driver allows local attackers to cause a denial of service via NULL pointer dereference during device disconnection.","url":"https://insights.sbomify.com/CVE-2026-98695/"}
