CyberRota Analysis
AI-GeneratedThe vulnerability affects GitHub's Ringpop-go implementation, where it fails to enforce configured LabelOptions limits on label maps received during SWIM membership changes. This oversight allows a network peer to submit excessive label data, leading to potential memory exhaustion and gossip-bandwidth consumption, which can render the hosting process unavailable. Organizations using affected versions should prioritize patching to mitigate availability risks associated with this vulnerability.

Original NVD Description
github.com/temporalio/ringpop-go enforces configured LabelOptions limits when an application changes the local node's labels, but affected versions do not apply those limits to label maps received in SWIM membership changes. A network peer that can reach a live Ringpop TChannel listener can repeatedly submit changes for distinct member addresses containing label keys, values, or counts that exceed the receiver's configured limits. Accepted labels are retained in the member list and disseminated to peers, allowing memory and gossip-bandwidth consumption to exceed configured bounds and potentially making the hosting process unavailable. The fix validates peer-supplied label maps before they are retained or disseminated. Availability only; no confidentiality or integrity impact was identified.
