CVE-2021-47060

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

Description The issue is related to the KVM (Kernel-based Virtual Machine) subsystem in the Linux kernel. It involves a problem with the kvm io bus unregister dev() function, which can lead to a deleted list entry dereference when attempting to continue iterating on coalesced zones after future entries have been deleted. This can occur if unregister dev() destroys all devices except the target device without informing the caller, resulting in a potential crash or other unintended behavior. The estimated number of potentially affected devices and details about real-world incidents are not provided.

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