Details

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

scsi: storvsc: Ratelimit warning logs to prevent VM denial of service

If there's a persistent error in the hypervisor, the SCSI warning for failed I/O can flood the kernel log and max out CPU utilization, preventing troubleshooting from the VM side. Ratelimit the warning so it doesn't DoS the VM.
