CVE-2023-3750 (GCVE-0-2023-3750)

Vulnerability from cvelistv5 – Published: 2023-07-24 15:19 – Updated: 2025-11-08 06:30

Title

Libvirt: improper locking in virstoragepoolobjlistsearch may lead to denial of service

Summary

A flaw was found in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as expected, resulting in a race condition and denial of service when attempting to lock the same object from another thread. This issue could allow clients connecting to the read-only socket to crash the libvirt daemon.

Severity

6.5 (Medium)
