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&#39;s memory, potentially leading to a denial of service or local privilege escalation.</p> <p><strong>Affected:</strong> Ubuntu:Pro:14.04:LTS: libvirt, Ubuntu:Pro:16.04:LTS: libvirt, Ubuntu:Pro:18.04:LTS: libvirt, Ubuntu:Pro:20.04:LTS: libvirt, Ubuntu:22.04:LTS: libvirt, Ubuntu:24.04:LTS: libvirt, Ubuntu:26.04:LTS: libvirt, Ubuntu:26.04:LTS: libvirt-hwe</p> <p>A flaw was found in libvirt.
