Lifecycle Timeline
2DescriptionCVE.org
A vulnerability was determined in ggml-org llama.cpp bec4772f6. This affects the function rpc_server::graph_compute of the file ggml/src/ggml-rpc/ggml-rpc.cpp of the component ggml-RPC Server. Executing a manipulation can lead to null pointer dereference. The attack may be launched remotely. The pull request to fix this issue awaits acceptance.
AnalysisAI
Null pointer dereference in llama.cpp's ggml-RPC server (commit bec4772f6) allows remote unauthenticated denial of service against any deployment exposing the RPC port to the network. The flaw resides in rpc_server::graph_compute, where a graph node with id=0 bypasses a conditional null check, enabling a single crafted TCP packet to crash the server process. …

Vulnerability AssessmentAI
| Exploitation | The ggml-RPC server must be explicitly enabled and running - it is not started by default in llama.cpp and requires operators to launch the rpc-server binary. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms remote, unauthenticated, low-complexity exploitation requiring no user interaction - a single malformed TCP packet suffices. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with TCP connectivity to the ggml-RPC port connects without authentication and sends a binary graph payload encoding a single graph node with id=0. The rpc_server::graph_compute function calls create_node, receives nullptr, and the exempted null check allows the null pointer to flow into computation, crashing the server process immediately. … |
| Remediation | The upstream fix is available as open pull request https://github.com/ggml-org/llama.cpp/pull/25670, but it has not yet been merged into a tagged release - no patched release version can be cited at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
