The callback, wcn36xx_dxe_tx_timer(), can\ntherefore be running past the teardown and use the wcn freed along\nwith the ieee80211_hw in wcn36xx_remove(): it takes wcn->dxe_lock,\nreads wcn->tx_ack_skb and passes wcn->hw to\nieee80211_tx_status_irqsafe().\n\nFix this by using timer_shutdown_sync(), which waits for a running\ncallback and also prevents the timer from being rearmed again. The\ntimer is set up again by wcn36xx_dxe_init() on the next start, so the\nstart/stop cycle is unaffected.\n\nThis issue was found by an in-house static analysis tool.","score":null,"severity":"unknown","published":"2026-10-06T08:44:32.912Z","modified":"2026-10-30T12:37:53.227Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"915298dbb766d2311b0822ab6ef24780def0bd53","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"e7f265d507ee55017b67ef4722df884468be1113","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"7ce1e55a439968a298a63d3199cb1c2636429746","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"15e59e377facc87ce82228279d88efaa89fdbca5","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"3edabc965bcce49cbb2ec1c2b91f8a555a8ec8bd","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"2bddc5d088cf430ecd913020472f1def32a36a3d","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"c0df0878e9110909cf0bec6080d72d36401a0c89","versionType":"git"},{"version":"fdf21cc3714939dd4327f3d664fe5863d15ccb31","status":"affected","lessThan":"d9be5e75530772fc31637070d51e5717d6aeaa2a","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98192"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"5.10","status":"affected"},{"version":"0","status":"unaffected","lessThan":"5.10","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.112","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.54","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.8","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-2026-98192"}],"remediation":[],"references":["https://git.kernel.org/stable/c/915298dbb766d2311b0822ab6ef24780def0bd53","https://git.kernel.org/stable/c/e7f265d507ee55017b67ef4722df884468be1113","https://git.kernel.org/stable/c/7ce1e55a439968a298a63d3199cb1c2636429746","https://git.kernel.org/stable/c/15e59e377facc87ce82228279d88efaa89fdbca5","https://git.kernel.org/stable/c/3edabc965bcce49cbb2ec1c2b91f8a555a8ec8bd","https://git.kernel.org/stable/c/2bddc5d088cf430ecd913020472f1def32a36a3d","https://git.kernel.org/stable/c/c0df0878e9110909cf0bec6080d72d36401a0c89","https://git.kernel.org/stable/c/d9be5e75530772fc31637070d51e5717d6aeaa2a"],"sources":[{"name":"CVE","id":"CVE-2026-98192","modified":"2026-10-30T12:37:53.227Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98192"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:00:59.849Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T00:10:33.488Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
