Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.14.14 and 1.15.8, a race condition in the Cilium agent can cause the agent to ignore labels that should be applied to a node. This could in turn cause CiliumClusterwideNetworkPolicies intended for nodes with the ignored label to not apply, leading to policy bypass. This issue has been patched in Cilium v1.14.14 and v1.15.8 As the underlying issue depends on a race condition, users unable to upgrade can restart the Cilium agent on affected nodes until the affected policies are confirmed to be working as expected.

GHSA-q7w8-72mr-vpgwPolicy bypass for Host Firewall policy due to race condition in Cilium agent2024-08-15ghsa · osvUS
### Impact A race condition in the Cilium agent can cause the agent to ignore labels that should be applied to a node. This could in turn cause CiliumClusterwideNetworkPolicies intended for nodes with the ignored label to not apply, leading to policy bypass. ### Patches This issue was fixed in https://github.com/cilium/cilium/pull/33511. This issue affects: - All versions of Cilium before v1.14.14 - Cilium v1.15 between v1.15.0 and v1.15.7 inclusive This issue has been patched in: - Cilium v1.14.14 - Cilium v1.15.8 ### Workarounds As the underlying issue depends on a race condition, users unable to upgrade can restart the Cilium agent on affected nodes until the affected policies are confirmed to be working as expected. ### Acknowledgements The Cilium community has worked together with members of Google and Isovalent to prepare these mitigations. Special thanks to @skmatti for raising and resolving this issue. ### For more information If you have any questions or comments about this advisory, please reach out on [Slack](https://docs.cilium.io/en/latest/community/community/#slack). If you think you have found a vulnerability affecting Cilium, we strongly encourage you to report it to our security mailing list at [security@cilium.io](mailto:security@cilium.io).
