Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw related to KVM (Kernel-based Virtual Machine) coalesced MMIO (Memory Mapped I/O) unregistration. Specifically, the target device is not properly destroyed and freed if the unregistration process fails, leading to a memory leak. The issue occurs within the
kvm io bus unregister dev() function, which does not destroy the target device as indicated in the code. This can result in an unreferenced object and a memory leak, as demonstrated by a bug report during testing.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
