CVE-2024-47825

CVE-2024-47825 affects Cilium's policy evaluation in versions prior to 1.14.16 and 1.15.10, where a rule denying a wide CIDR (> /32) could be ignored if a narrower rule references CIDRSet or toFQDN and uses enableDefaultDeny: false or toEntities: all. The issue is mitigated by upgrading to Cil...

CVE-2024-47825 CIDR deny policies may not take effect when a more narrow CIDR allow is present

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Starting in version 1.14.0 and prior to versions 1.14.16 and 1.15.10, a policy rule denying a prefix that is broader than /32 may be ignored if there is a policy rule referencing a more narrow prefix CIDRSe...

BIT-CILIUM-OPERATOR-2024-42487 Cilium's Gateway API route matching order contradicts specification

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In the 1.15 branch prior to 1.15.8 and the 1.16 branch prior to 1.16.1, Gateway API HTTPRoutes and GRPCRoutes do not follow the match precedence specified in the Gateway API specification. In particular,...

BIT-CILIUM-OPERATOR-2024-42488 Cilium agent's race condition may lead to policy bypass for Host Firewall policy

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...

CVE-2024-42486

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In versions on the 1.15.x branch prior to 1.15.8 and the 1.16.x branch prior to 1.16.1, ReferenceGrant changes are not correctly propagated in Cilium's GatewayAPI controller, which could lead to Gateway...
