In the Linux kernel, the following vulnerability has been resolved:
iommu/riscv: Serialize command queue publishing
Serialize command queue publishing so software producer state advances only
after a command is written and the hardware tail is updated. Wait for
hardware consumption outside the queue lock when the command queue is full
so other CPUs are not blocked behind a long poll.
