Name of the Vulnerable Software and Affected Versions libvirt (affected versions not specified)

Description A flaw was found in the virStoragePoolObjListSearch function of libvirt, which does not return a locked pool as expected. This results in a race condition and denial of service when attempting to lock the same object from another thread. The issue could allow clients connecting to the read-only socket to crash the libvirt daemon. The flaw is caused by synchronization errors when using a shared resource, and its exploitation could allow a remote attacker to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
