Description
In the Linux kernel, the following vulnerability has been resolved:
s390/ism: Fix UAF of sba and ieq during ism_dev_exit()
A ism interrupt handler can be active in parallel with ism_dev_exit(),
accessing freed data structures.
No new interrupts will be generated after unregister_ieq(). Drain ongoing
interrupt handlers by free_irq(), before freeing ism data structures.
