NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-log-debuginfo package and not the libvirt-daemon-log-debuginfo package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer. This heap buffer overflow can corrupt the root libvirt daemon's memory, potentially leading to a denial of service or local privilege escalation.
