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tests.","score":null,"severity":"unknown","published":"2026-10-18T15:46:16.794Z","modified":"2026-11-06T17:15:04.213Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"d6d458d42e1e1544a18f37f1d5c840e00d5261b9","status":"affected","lessThan":"39a2c4e5e606cf49b83595971b449b3fb80743c6","versionType":"git"},{"version":"d6d458d42e1e1544a18f37f1d5c840e00d5261b9","status":"affected","lessThan":"47d60ea801fc333a10c576691eca2e7840b02d3d","versionType":"git"},{"version":"d6d458d42e1e1544a18f37f1d5c840e00d5261b9","status":"affected","lessThan":"12f5d8b85a66a0ac08d082517d92ce136f8c0d42","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98692"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"6.14","status":"affected"},{"version":"0","status":"unaffected","lessThan":"6.14","versionType":"semver"},{"version":"6.18.61","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98692"}],"remediation":[],"references":["https://git.kernel.org/stable/c/39a2c4e5e606cf49b83595971b449b3fb80743c6","https://git.kernel.org/stable/c/47d60ea801fc333a10c576691eca2e7840b02d3d","https://git.kernel.org/stable/c/12f5d8b85a66a0ac08d082517d92ce136f8c0d42"],"sources":[{"name":"CVE","id":"CVE-2026-98692","modified":"2026-11-06T17:15:04.213Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98692"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-11-06T17:58:33.571Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:10:33.488Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-07T02:35:37.985Z","attemptedAt":"2026-11-07T02:35:37.985Z"},{"source":"GHSA","status":"available","checkedAt":"2026-11-07T02:35:37.854Z","attemptedAt":"2026-11-07T02:35:37.854Z"},{"source":"EUVD","status":"available","checkedAt":"2026-11-07T02:35:38.465Z","attemptedAt":"2026-11-07T02:35:38.465Z"},{"source":"EPSS","status":"available","checkedAt":"2026-11-07T02:35:37.567Z","attemptedAt":"2026-11-07T02:35:37.567Z"}],"evidence":[{"source":"FIRST EPSS","id":"CVE-2026-98692","url":"https://www.first.org/epss/","probability":0.00155,"percentile":0.04727,"date":"2026-11-06","checkedAt":"2026-11-07T02:35:37.567Z"},{"source":"GitHub Advisory Database","id":"GHSA-j976-jwv6-gqm2","url":"https://github.com/advisories/GHSA-j976-jwv6-gqm2","modified":"2026-11-06T18:35:58Z","checkedAt":"2026-11-07T02:35:37.854Z"},{"source":"NVD","id":"CVE-2026-98692","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98692","modified":"2026-11-06T18:18:29.917","checkedAt":"2026-11-07T02:35:37.985Z"},{"source":"ENISA EUVD","id":"EUVD-2026-103946","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-103946","modified":"Nov 6, 2026, 5:15:04 PM","checkedAt":"2026-11-07T02:35:38.465Z"}],"aiSummary":null}
