Description
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.
Statement
The versions of libvirt as shipped with Red Hat Enterprise Linux 6, 7, and 8 are not affected by this flaw, as they did not include the unlocking refactor that introduced the bug (upstream commit 0c4b391e2a9).
