CVE-2025-21690

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue concerns a vulnerability in the Linux kernel where a persistent error in the hypervisor can cause the SCSI warning for failed I/O to flood the kernel log, maximizing CPU utilization and preventing troubleshooting from the VM side. This can lead to a denial of service (DoS) of the virtual machine. The warning logs have been rate-limited to prevent this issue.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
