{"identifier":"CVE-2026-98112","cve":{"id":"CVE-2026-98112","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: fix listener task lifetime on netdev events\n\nThe listener thread exits when its listening socket is shutdown. The\nnetdevice notifier shuts down the socket before calling kthread_stop(), so\nthe task_struct can be freed before kthread_stop() gets its reference.\n\nCreate the listener in a stopped state and hold an extra task_struct\nreference until kthread_stop_put() completes. Also stop and release\nlisteners before freeing their interface records during TCP teardown.","published":"2026-09-25T11:17:42.340000+00:00","modified":"2026-10-28T18:49:41.733000+00:00","status":"Analyzed","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_version":"3.1","affected":[{"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionStartExcluding":"","versionEndIncluding":"","versionEndExcluding":"7.2.7"},{"criteria":"cpe:2.3:o:linux:linux_kernel:7.3:rc1:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"","versionEndExcluding":""}],"weaknesses":["CWE-362","CWE-416"],"references":[{"url":"https://git.kernel.org/stable/c/40581f10c1e56238b157af5f260b8f9518a0cbc1","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/a506290f59e1c6ce9ac0a13158640bb8fee93471","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":5.9}]},"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.19","versionEndExcluding":"7.2.7","matchCriteriaId":"19917B2D-B4B2-4416-A482-9C7C4929A921"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:7.3:rc1:*:*:*:*:*:*","matchCriteriaId":"11E35E1B-5DB4-4AB9-9706-CD73B799EADF"}]}]}],"source":"nvd","retrieved_at":"2026-10-28T21:19:37.456011+00:00","exploited":false,"kev_stale":false,"products":["linux / linux kernel"],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00093,"percentile":0.0053,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"git.kernel.org","source_url":"https://git.kernel.org/stable/c/40581f10c1e56238b157af5f260b8f9518a0cbc1","investigate_url":"https://investigate.aeglixmind.com/#git.kernel.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-98112","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-98112","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-98112","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
