{"schema":"threatline.record/2","record":{"id":"CVE-2026-98544","aliases":[],"summary":"bna: prevent IOC timer rearm during teardown","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbna: prevent IOC timer 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.","categories":["Operating
