Security readout for executives and security teams
Plain-English summary
CVE-2022-43222 is a denial-of-service risk in Open5GS v2.4.11. A crafted PFCP packet can trigger a memory leak in the SMF PFCP path code, potentially degrading or stopping service availability. The record rates this high because it is network-reachable and needs no authentication or user interaction.
Executive priority
Treat as a high-priority availability issue for any Open5GS v2.4.11 environment. It threatens service continuity, but current source evidence does not show data theft, integrity compromise, or active exploitation.
Technical view
The CVE describes CWE-401 memory leak behavior in open5gs v2.4.11, specifically src/smf/pfcp-path.c. CVSS 3.1 is 7.5 with AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, indicating remote unauthenticated availability impact only. The provided sources do not identify CPEs, affected version ranges beyond v2.4.11, or a fixed release.
Likely exposure
Exposure is most likely where Open5GS v2.4.11 SMF/PFCP functionality is deployed and PFCP traffic can reach it over the network. The source bundle does not provide CPEs or broader affected-version evidence.
Exploitation context
The CVE says denial of service is possible through a crafted PFCP packet. CISA KEV is false, and the provided sources do not document active exploitation, public weaponization, or exploitation in the wild.
Researcher notes
Evidence is sparse. The record identifies one affected version and component, a memory leak class, and a GitHub bug report reference. It does not provide a fix commit, complete affected range, exploit maturity, or vendor remediation details.
Mitigation direction
- Identify any Open5GS v2.4.11 deployments, especially SMF/PFCP components.
- Check Open5GS or vendor guidance for fixed versions or official patches.
- Restrict PFCP reachability to trusted peers and management networks only.
- Monitor SMF memory growth, restarts, and availability until remediation is confirmed.
Validation and detection
- Confirm Open5GS versions deployed in production, lab, and backup environments.
- Verify whether affected SMF/PFCP code is present and enabled.
- Review network controls limiting PFCP traffic sources.
- Check logs and monitoring for SMF memory exhaustion or unexplained DoS symptoms.
