CVE-2023-41332

Summary

CVE-2023-41332 is a vulnerability affecting Cilium, a networking, observability, and security solution. When Cilium's Layer 7 proxy is disabled in Cilium clusters, the creation of workloads with specific annotations causes the Cilium agent on the node to segfault, leading to a denial of service. This issue is limited to the affected node, but an attacker may be able to exploit it by scheduling workloads on their target node. The vulnerability has been resolved in Cilium versions 1.14.2, 1.13.7, and 1.12.14. Users unable to upgrade can mitigate the risk by enabling the Layer 7 proxy.
