BIT-HUBBLE-RELAY-2023-27594 Cilium vulnerable to potential network policy bypass when routing IPv6 traffic

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.11.15, 1.12.8, and 1.13.1, under specific conditions, Cilium may misattribute the source IP address of traffic to a cluster, identifying external traffic as coming from the host on which...

BIT-HUBBLE-RELAY-2023-27595 Cilium eBPF filters may be temporarily removed during agent restart

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In version 1.13.0, when Cilium is started, there is a short period when Cilium eBPF programs are not attached to the host. During this period, the host does not implement any of Cilium's featureset. This ca...

BIT-HUBBLE-RELAY-2023-29002 Debug mode leaks confidential data in Cilium

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. When run in debug mode, Cilium will log the contents of the cilium-secrets namespace. This could include data such as TLS private keys for Ingress and GatewayAPI resources. An attacker with access to debug...

BIT-HUBBLE-RELAY-2023-30851 Potential HTTP policy bypass when using header rules in Cilium

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. This issue only impacts users who have a HTTP policy that applies to multiple toEndpoints AND have an allow-all rule in place that affects only one of those endpoints. In such cases, a wildcard rule will be...

BIT-HUBBLE-RELAY-2023-34242 Cilium vulnerable to information leakage via incorrect ReferenceGrant handling

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to version 1.13.4, when Gateway API is enabled in Cilium, the absence of a check on the namespace in which a ReferenceGrant is created could result in Cilium unintentionally gaining visibility of...

BIT-HUBBLE-RELAY-2023-39347 Cilium NetworkPolicy bypass via pod labels

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to update pod labels can cause Cilium to apply incorrect network policies. This issue arises due to the fact that on pod update, Cilium incorrectly uses user-provided pod labels...

BIT-HUBBLE-RELAY-2024-25630

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. For Cilium users who are using CRDs to store Cilium state the default configuration and Wireguard transparent encryption, traffic to/from the Ingress and health endpoints is not encrypted. This issue affect...

BIT-HUBBLE-RELAY-2024-25631

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. For Cilium users who have enabled an external kvstore and Wireguard transparent encryption, traffic between pods in the affected cluster is not encrypted. This issue affects Cilium v1.14 before v1.14.7 and...

BIT-HUBBLE-RELAY-2024-28249

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.13.13, 1.14.8, and 1.15.2, in Cilium clusters with IPsec enabled and traffic matching Layer 7 policies, IPsec-eligible traffic between a node's Envoy proxy and pods on other nodes is sen...

BIT-HUBBLE-RELAY-2024-28250

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.14.0 and prior to versions 1.14.8 and 1.15.2, In Cilium clusters with WireGuard enabled and traffic matching Layer 7 policies Wireguard-eligible traffic that is sent between a node's...

BIT-HUBBLE-RELAY-2024-28860

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Users of IPsec transparent encryption in Cilium may be vulnerable to cryptographic attacks that render the transparent encryption ineffective. In particular, Cilium is vulnerable to chosen plaintext, key...

kernel: improper input validation may lead to privilege escalation

An out-of-bounds OOB memory access flaw was found in the Linux kernel's eBPF due to an Improper Input Validation. This flaw allows a local attacker with a special privilege to crash the system or leak internal information...

DEBIAN-CVE-2024-35860

In the Linux kernel, the following vulnerability has been resolved: bpf: support deferring bpflink dealloc to after RCU grace period BPF link for some program types is passed as a "context" which can be used by those BPF programs to look up additional information. E.g., for multi-kprobes and...

BIT-CILIUM-2023-27593 cilium-agent container can access the host via `hostPath` mount

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to versions 1.11.15, 1.12.8, and 1.13.1, an attacker with access to a Cilium agent pod can write to /opt/cni/bin due to a hostPath mount of that directory in the agent pod. By replacing the CNI binary...
