Description OSIDB Bzimport 2025-02-10 17:01:26 UTC 
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.
