An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-98130 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-98130/ (Markdown: https://insights.sbomify.com/CVE-2026-98130/index.md)","id":"CVE-2026-98130","markdown":"https://insights.sbomify.com/CVE-2026-98130/index.md","name":"CVE-2026-98130","record":{"aliases":["AZL-104232","BELL-CVE-2026-98130","DEBIAN-CVE-2026-98130","GHSA-8fp7-88m9-24jc","UBUNTU-CVE-2026-98130"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel SCTP","requires_auth":"none","summary":"A race condition in the Linux kernel SCTP timer handling can lead to use-after-free, potentially allowing attackers to execute code or escalate privileges.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsctp: fix a TOCTOU race in SCTP_CMD_TIMER_START\n\nThe SCTP_CMD_TIMER_START handler checks timer_pending() before calling\ntimer_reduce().
