This vulnerability stems from a lack of bounds checking on the notifys vector, which handles incoming peer notification frames. An unauthenticated attacker can exploit this by repeatedly transmitting 1 MB notify frames to the handshake RPC port. Because the system does not cap the size or count of these frames, the process memory usage grows monotonically until the operating system's out-of-memory (OOM) killer is invoked to terminate the engine. This results in a persistent denial-of-service condition, impacting the availability of the transfer service. Defenders should prioritize updating to the next patched release once available and implement rate limiting on the RPC handshake port to mitigate exploitation attempts.

Impact

Successful exploitation results in the immediate termination of the Mooncake transfer engine process via the system OOM killer, causing a denial-of-service. This impacts any infrastructure relying on Mooncake for data transfer operations. No data modification or execution is currently associated with this memory exhaustion vulnerability, but the interruption of service could disrupt critical business processes.

Recommendation

• Monitor RPC traffic to the handshake port for high volumes of large frames (1 MB) originating from unauthorized sources.
• Apply network-level rate limiting or connection throttling on the handshake RPC port as an immediate defensive measure.
• Monitor system logs for OOM killer events or unexpected crashes of the Mooncake process.
• Upgrade the Mooncake transfer engine to a version beyond 0.3.13.post1 immediately upon vendor release.

This flaw allows unauthenticated remote attackers to interact with the service over its TCP transport data port. By crafting a malicious SessionHeader containing arbitrary address and size fields, an attacker can issue READ or WRITE opcodes. These operations enable the unauthorized disclosure of sensitive internal information, such as KV cache contents, prompts, and system secrets. Furthermore, the ability to perform arbitrary memory writes allows for potential memory corruption, which may be leveraged to achieve remote code execution on the host running the transfer engine. Given the severity of this vulnerability and the lack of authentication requirements, defenders should prioritize patching to version 0.3.13 or later.

Impact

Successful exploitation of CVE-2026-103764 results in full compromise of the affected process memory. Impact includes the theft of sensitive proprietary data, such as cached prompts and secrets, and potential full system compromise via arbitrary code execution. This impacts any environment deploying Mooncake transfer engine versions prior to 0.3.13 exposed to untrusted network segments.

Recommendation

• Upgrade the Mooncake transfer engine to version 0.3.13 or later immediately to address the underlying pointer dereference flaw.
• Restrict network access to the Mooncake TCP transport data port to trusted IP addresses only, reducing the attack surface until patches can be applied.
• Monitor network traffic for anomalous sequences targeting the transfer engine port, specifically looking for header anomalies or large-scale data transfer patterns indicative of memory dumping.
