# CVE-2022-0897: Race condition in libvirt > An unprivileged user can crash the libvirt network filter daemon by exploiting a race condition in the nwfilter driver. - **Severity:** Medium 4.3 (`CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 25 Mar 2022 - **Updated:** 2 Aug 2024 - **Also known as:** ALSA-2022:8003, CLSA-2022-1669237947, CLSA-2022-1669238254, DEBIAN-CVE-2022-0897, GHSA-4r2g-j5rc-7wqf, OESA-2022-1722, RHSA-2022:8003, RLSA-2022:8003, SUSE-SU-2022:1540-1, SUSE-SU-2022:1549-1, SUSE-SU-2023:2754-1, UBUNTU-CVE-2022-0897, openSUSE-SU-2024:11972-1 ## What is CVE-2022-0897? CVE-2022-0897 is a medium-severity vulnerability in Netapp Ontap Select Deploy Administration Utility, published on 25 Mar 2022. Any signed-in user can exploit it over the network, with no action from the victim. ### Official description 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).

What it is: CVE-2022-0897 is a medium-severity vulnerability in Netapp Ontap Select Deploy Administration Utility, published on 25 Mar 2022. Any signed-in user can exploit it over the network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2022-0897 in the wild and no public exploit code. Affected product: Netapp Ontap Select Deploy Administration Utility. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
