VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 5.8.10
Description: An issue in the Linux kernel is related to a memory leak in the kvm io bus unregister dev function, located in virt/kvm/kvm main.c, which occurs upon a kmalloc failure. This issue can be exploited to cause a denial of service.
Recommendations: For Linux kernel versions prior to 5.8.10, update to version 5.8.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the kvm io bus unregister dev function to minimize the risk of exploitation.
