Summary
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.
