{"schema":"threatline.record/2","record":{"id":"CVE-2026-98692","aliases":[],"summary":"thunderbolt: Make the DP tunnel activation callback mandatory","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Make the DP tunnel activation callback mandatory\n\ntb_tunnel_alloc_dp() takes an optional callback which is run from\ndprx_work once the DPRX capabilities read has completed. Without that\ncallback tb_dp_dprx_start() reads the capabilities synchronously and\nnever queues the work. It however always takes a tunnel reference which\nis only dropped by dprx_work itself or by tb_dp_dprx_stop() when\ncancel_delayed_work() actually canceled that work. That reference is\nthus leaked for every tunnel without a callback.\n\nThe only tunnels without one are those from tb_tunnel_discover_dp(),\nwhich are activated again when restoring from hibernation.\nPass the callback to tb_tunnel_discover_dp() as well and drop the\nsynchronous path such that the DPRX capabilities are always read from\ndprx_work. Hibernation restore then also no longer blocks for up to 12\nseconds while waiting for that read to complete.\n\nAlso fix up the KUnit tests.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98692","source_modified_at":"2026-10-19T09:24:02.145Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"d6d458d42e1e1544a18f37f1d5c840e00d5261b9","lessThan":"47d60ea801fc333a10c576691eca2e7840b02d3d","status":"affected","versionType":"git"},{"version":"d6d458d42e1e1544a18f37f1d5c840e00d5261b9","lessThan":"12f5d8b85a66a0ac08d082517d92ce136f8c0d42","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98692","source_modified_at":"2026-10-19T09:24:02.145Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.14","status":"affected"},{"version":"0","lessThan":"6.14","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98692","source_modified_at":"2026-10-19T09:24:02.145Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"47d60ea801fc333a10c576691eca2e7840b02d3d","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98692","source_modified_at":"2026-10-19T09:24:02.145Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"12f5d8b85a66a0ac08d082517d92ce136f8c0d42","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00155,"percentile":0.04322,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:46:16.794Z","modified_at":"2026-10-19T09:24:02.145Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98692","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:24:02.145Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98692","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/47d60ea801fc333a10c576691eca2e7840b02d3d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/12f5d8b85a66a0ac08d082517d92ce136f8c0d42"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:24:02.145Z","content_hash":"1a43fd9863e9efa2584a77a6f668bfc1d222514bebc81c76778334cc66c8ff55"}}
