An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read-only connection to cause a memory leak in the domstats command, resulting in a potential denial of service.

Se descubrió un problema en la función qemuDomainGetStatsIOThread en el archivo qemu/qemu_driver.c en libvirt versiones 4.10.0 hasta 6.x anteriores a 6.1.0. Se encontró una pérdida de memoria en la API libDirt de virDomainListGetStats que es responsable de recuperar las estadísticas del dominio al administrar invitados de QEMU. Este fallo permite a los usuarios no privilegiados con una conexión de solo lectura causar una pérdida de memoria en el comando domstats, resultando en una posible denegación de servicio.
