The following commit has been merged in the master branch: commit abac3ac97fe8734b620e7322a116450d7f90aa43 Author: Vladislav Efanov <VEfanov(a)ispras.ru> Date: Fri May 26 19:16:32 2023 +0300 batman-adv: Broken sync while rescheduling delayed work Syzkaller got a lot of crashes like: KASAN: use-after-free Write in *_timers* All of these crashes point to the same memory area: The buggy address belongs to the object at ffff88801f870000 which belongs to the cache kmalloc-8k of size 8192 The buggy address is located 5320 bytes inside of 8192-byte region [ffff88801f870000, ffff88801f872000) This area belongs to : batadv_priv->batadv_priv_dat->delayed_work->timer_list The reason for these issues is the lack of synchronization. Delayed work (batadv_dat_purge) schedules new timer/work while the device is being deleted. As the result new timer/delayed work is set after cancel_delayed_work_sync() was called. So after the device is freed the timer list contains pointer to already freed memory. Found by Linux Verification Center (linuxtesting.org) with syzkaller.
