rearm during teardown\n\nbna: prevent IOC timer rearm during teardown\n\nbnad_pci_remove() and the probe disable_ioceth path call\ntimer_delete_sync() for ioc_timer, sem_timer and hb_timer, but not for\niocpf_timer.  bnad_iocpf_timeout() then takes bnad->bna_lock after\nfree_netdev() has freed the struct bnad.\n\nDeleting iocpf_timer last does not fix this.  sem_timer and\niocpf_timer rearm each other: bnad_iocpf_sem_timeout() can arm\niocpf_timer, and bnad_iocpf_timeout() arms sem_timer from\nbfa_ioc_hw_sem_get() when the semaphore is busy.\ntimer_delete_sync() only waits out its own callback.\nbnad_ioceth_disable() can time out and leave that callback live.\n\nShut all four IOC timers down with timer_shutdown_sync() on both\npaths, so a later mod_timer() is ignored.\n\nThis issue was identified during our ongoing static-analysis research\nwhile reviewing kernel code.","score":null,"severity":"unknown","published":"2026-10-18T15:18:12.964Z","modified":"2026-10-30T12:38:23.865Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"8160cd1ec527caedd36c36f948234e834cd086e6","versionType":"git"},{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"3614582375fc4407e09ff42ff178a045e2fe6e8f","versionType":"git"},{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"f04cbdfac9b8284146995ab7ba0d054ad1d20ec6","versionType":"git"},{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"28e32ace754b57534ef0ca0fb99bcbea5b13ba2a","versionType":"git"},{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"4d97a141e85a034566c33c7ed854c8a3e8a268f1","versionType":"git"},{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"e09d1c6729ee4a7812128902d9274ff565f958b8","versionType":"git"},{"version":"1d32f7696286eef9e5644eb57e79a36756274357","status":"affected","lessThan":"77b1718e39e5c9f6956fb60807326af20baf889d","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98544"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"2.6.38","status":"affected"},{"version":"0","status":"unaffected","lessThan":"2.6.38","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":"6.18.55","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.9","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-2026-98544"}],"remediation":[],"references":["https://git.kernel.org/stable/c/8160cd1ec527caedd36c36f948234e834cd086e6","https://git.kernel.org/stable/c/3614582375fc4407e09ff42ff178a045e2fe6e8f","https://git.kernel.org/stable/c/f04cbdfac9b8284146995ab7ba0d054ad1d20ec6","https://git.kernel.org/stable/c/28e32ace754b57534ef0ca0fb99bcbea5b13ba2a","https://git.kernel.org/stable/c/4d97a141e85a034566c33c7ed854c8a3e8a268f1","https://git.kernel.org/stable/c/e09d1c6729ee4a7812128902d9274ff565f958b8","https://git.kernel.org/stable/c/77b1718e39e5c9f6956fb60807326af20baf889d"],"sources":[{"name":"CVE","id":"CVE-2026-98544","modified":"2026-10-30T12:38:23.865Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98544"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:01:45.751Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:35:33.875Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
