Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Cilium (github.com/cilium/cilium) versions before 1.12.14, from 1.13.0 before 1.13.7, and from 1.14.0 before 1.14.2 are vulnerable. In clusters with the Layer 7 proxy disabled, a user who creates workloads with a specific proxy-visibility annotation can crash the Cilium agent on the node hosting them, stopping it from processing workload changes and blocking new workloads on that node. Upgrade to 1.12.14, 1.13.7, 1.14.2, or later; alternatively, enable the Layer 7 proxy.
