  "description": "llama.cpp is an inference of several LLM models in C/C\u002B\u002B. Prior to version b8492, the RPC backend\u0027s deserialize_tensor() skips all bounds validation when a tensor\u0027s buffer field is 0. An unauthenticated attacker can read and write arbitrary process memory via crafted GRAPH_COMPUTE messages. Combined with pointer leaks from ALLOC_BUFFER/BUFFER_GET_BASE, this gives full ASLR bypass and remote code execution. No authentication required, just TCP access to the RPC server port. This issue has been patched in version b8492.",
