In the Linux kernel, the following vulnerability has been resolved:

iommu/arm-smmu: Don't unregister on shutdown

Michael Walle says he noticed the following stack trace while performing a shutdown with "reboot -f". He suggests he got "lucky" and just hit the correct spot for the reboot while there was a packet transmission in flight.

This appears to be reproducible when the board has a fixed IP address, is ping flooded from another host, and "reboot -f" is used.
