"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: isci: Fix use-after-free in device removal path\n\nThe ISCI completion tasklet is initialized in isci_host_alloc()\n(drivers/scsi/isci/init.c:496) and scheduled from both MSI-X and legacy\ninterrupt handlers (drivers/scsi/isci/host.c:223,613).\n\nisci_host_deinit() stops the controller and waits for stop completion,\nbut it never kills completion_tasklet before teardown continues. A\ntop-of-function tasklet_kill() is not sufficient here: interrupts are\nonly disabled when isci_host_stop_complete() runs, so until\nwait_for_stop() returns the IRQ handlers can still requeue the\ntasklet. The tasklet callback also re-enables interrupts after draining\ncompletions, so killing the tasklet before the source is quiesced leaves\nthe same race open.\n\nOnce wait_for_stop() returns, no further IRQ-driven scheduling can\noccur. Kill completion_tasklet there so teardown cannot race a queued\ntasklet running on a dead ihost. On remove or unload, the stale callback\ncan otherwise dereference ihost and touch ihost->smu_registers after the\nhost lifetime ends.\n\nA UML + KASAN analogue reproduced the failure class both with no\ntasklet_kill() and with tasklet_kill() placed before source quiesce, and\nstayed clean once the kill happened after quiescing the scheduling\nsource.\n\nThis mirrors commit f6ab594672d4 (\"scsi: aic94xx: fix use-after-free in\ndevice removal path\"), but ISCI needs the kill after wait_for_stop()."
