OESA-2022-1722 (CVE-2022-0897)

Vulnerability from osv_openeuler – Published: 2022-06-24 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

libvirt security update

Details

Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). The main package includes the libvirtd server exporting the virtualization support.

Security Fix(es):

A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt’s API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).(CVE-2022-0897)

Severity

4.3 (Medium)

CVE-2022-0897 (GCVE-0-2022-0897)

Vulnerability from cvelistv5 – Published: 2022-03-25 00:00 – Updated: 2024-08-02 23:47

Summary

A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt's API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).
