CVE-2023-3750 'virStoragePoolObjListSearch' explicitly documents that it's returning a pointer to a locked and ref'd pool that maches the lookup function. This was not the case as in commit 0c4b391e2a9 (released in libvirt-8.3.0) the code was accidentally converted to use 'VIR_LOCK_GUARD' which auto-unlocked it when leaving the scope, even when the code was originally "leaking" the lock. Revert the corresponding conversion and add a comment that this function is intentionally leaking a locked object.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
