  "details": "### Impact\nAn error in 32 bit signed and unsigned types in the calculation of available gas in the CALL operations (including DELEGATECALL) results in incorrect gas being passed into called contracts and incorrect gas being returned after call execution.  Where the amount of gas makes a difference in the success or failure, or if the gas is a negative 64 bit value, the execution will result in a different state root than expected, resulting in a consensus failure in networks with multiple EVM implementations. \n\nIn networks with a single EVM implementation this can be used to execute with significantly more gas than then transaction requested, possibly exceeding gas limitations. \n\n### Patches\nVersion 22.7.1 contains a fix, ensuring that excess gas will not be allocated to inner transaction calls and correcting the excess gas errors.\n\n### Workarounds\nReverting to version 22.1.3 or earlier will prevent incorrect execution. However many ethereum mainnet networks require changes in more recent versions of Besu and should not use older versions of besu and should instead use the patched version.  \n\nEthereum Classic and other networks not depending on a Proof of Stake transition should function fine with version 22.1.3 or earlier.\n\n### For more information\nIssue was found by [Martin Holst Swende](https://github.com/holiman) using [goevmlab](https://github.com/holiman/goevmlab), it is believed that no production networks have transactions that would trigger this failure.\n\n",

  "details": "**Summary**\nA vulnerability in the readField function allows a malicious or compromised AMQP server to trigger an unhandled runtime panic in the client application, leading to an immediate crash of the entire process.\n\n**Details**\nWhen parsing incoming AMQP frames, the `readField` function processes byte-array fields (type tag `\u0027x\u0027`) by reading a 32-bit big-endian integer to determine the length of the data payload.\n\n```go\n// read.go:253-263\ncase \u0027x\u0027:\n    var len int32\n    if err = binary.Read(r, binary.BigEndian, \u0026len); err != nil {\n        return nil, err\n    }\n    value := make([]byte, len)  // PANICS if len \u003c 0\n```\n\nIf a server transmits a length value of `0xFFFFFFFF`, it is interpreted by the client as a signed 32-bit integer with a value of `-1`. Passing a negative integer to Go\u0027s built-in make() function for slice allocation triggers an unrecoverable runtime panic (panic: len out of range).\n\nBecause the reader goroutine handles network I/O without an explicit recover() wrapper, this panic propagates up to the runtime root, abruptly terminating the host application.\n\n**Attack Vector / Exploitation Scenario**\nAn attacker capable of spoofing, compromising, or controlling an AMQP broker can exploit this flaw during two primary phases:\n\n1. Connection Establishment: Sending a malicious connection.start handshake frame containing server-properties with an \u0027x\u0027 type field assigned a negative length.\n2. Message Delivery: Delivering a message payload where the header table contains a malformed field matching the criteria above.\n\n**Impact**\nAvailability: High. A single malformed frame can reliably crash the client process, resulting in a persistent Denial of Service (DoS) if the client automatically reconnects and receives the same payload.",

  "details": "## Summary\n\nInteger truncation of tensor dimensions in vLLM\u0027s GGUF dequantize kernels (`csrc/quantization/gguf/gguf_kernel.cu`) causes partial tensor processing. The output tensor is allocated at full size via `torch::empty` (uninitialized memory), but the dequantize CUDA kernel processes only a truncated number of elements. The unfilled portion of the output tensor retains whatever was previously in GPU memory. In multi-tenant inference deployments, this residual GPU memory may contain tensor data from other users\u0027 inference requests, constituting information disclosure.\n\n## Root Cause\n\nThe `to_cuda_ggml_t` function pointer type at `ggml-common.h:1067` declares its element count parameter as `int` (32-bit):\n\n```cpp\nusing to_cuda_ggml_t = void (*)(const void * __restrict__ x,\n                                dst_t * __restrict__ y,\n                                int k,              // 32-bit\n                                cudaStream_t stream);\n```\n\nAll dequantize kernel functions (`dequantize_block_cuda`, `dequantize_row_q2_K_cuda`, etc. in `dequantize.cuh`) inherit this `int k` parameter and use it as the kernel launch grid size:\n\n```cpp\nstatic void dequantize_block_cuda(..., const int k, cudaStream_t stream) {\n    const int num_blocks = (k + 2*CUDA_DEQUANTIZE_BLOCK_SIZE - 1) / (2*CUDA_DEQUANTIZE_BLOCK_SIZE);\n    dequantize_block\u003c\u003c\u003cnum_blocks, CUDA_DEQUANTIZE_BLOCK_SIZE, 0, stream\u003e\u003e\u003e(vx, y, k);\n}\n```\n\nIn `ggml_dequantize()` at `gguf_kernel.cu:85`, the caller passes `m * n` (an `int64_t` product) to this `int k` parameter:\n\n```cpp\nat::Tensor DW = torch::empty({m, n}, options);    // line 80: full-size, UNINITIALIZED\n// ...\nto_cuda((void*)W.data_ptr(), (scalar_t*)DW.data_ptr(), m * n, stream);  // line 85: m*n truncated to int\n```\n\nWhen `m * n \u003e INT_MAX`, the truncated `k` is smaller than the actual tensor size. The kernel processes `k` elements. The remaining `(m * n) - k` elements in `DW` are never written and contain stale GPU memory.\n\nThis is a single root cause -- the `int` type on the `k` parameter in `to_cuda_ggml_t` -- with a single fix: change `int k` to `int64_t k`. All dequantize functions inherit this type through the same typedef.\n\n## Affected Functions\n\nAll in `csrc/quantization/gguf/gguf_kernel.cu`:\n\n| Function | Line | Allocation | Info Disclosure? |\n|----------|------|-----------|-----------------|\n| `ggml_dequantize` | 74 | `torch::empty({m, n})` at line 80 | Yes -- `m*n` truncated to `int k` at line 85 |\n| `ggml_mul_mat_vec_a8` | 91 | `torch::empty({vecs, row})` at line 99 | Yes -- `int col = X.sizes()[1]` at line 94 |\n| `ggml_mul_mat_a8` | 207 | `torch::empty({batch, row})` at line 215 | Yes -- `int col = X.sizes()[1]` at line 210 |\n| `ggml_moe_a8` | 279 | `torch::empty({tokens*top_k, row})` at line 289 | Yes -- `int col = X.sizes()[1]` at line 285 |\n\nAll four functions allocate output tensors with `torch::empty` (uninitialized) and then run CUDA kernels that use truncated dimension values as loop bounds. The unfilled portion of each output tensor retains stale GPU memory.\n\n`ggml_moe_a8_vec` (line 382) uses `torch::zeros` instead of `torch::empty`, so it is not affected by the info disclosure variant.\n\n## Impact: Information Disclosure in Multi-Tenant Serving\n\nvLLM is designed for multi-tenant inference serving. GPU memory is reused across requests from different users. When the dequantize kernel partially fills an output tensor:\n\n1. The output tensor `DW` is allocated with `torch::empty` -- the buffer contains whatever was previously in that GPU memory region\n2. The dequantize kernel fills only a truncated portion of the buffer\n3. The unfilled portion retains residual data from prior GPU operations, which may include tensor data from other users\u0027 inference requests\n4. The contaminated tensor proceeds through the model computation\n5. No error or warning is generated -- the partial fill is silent\n\nThis is a confidentiality violation. In shared inference deployments (the primary vLLM use case), one user\u0027s inference data can leak into another user\u0027s model computation through residual GPU memory.\n\n## Attacker Control\n\nThe attacker crafts a GGUF model file with weight tensor dimensions whose product exceeds `INT_MAX` (e.g., a matrix with shape `[65536, 65536]` gives `m * n = 4,294,967,296`). The model is hosted on HuggingFace or any model hub. The victim loads the model with vLLM for inference serving. The truncation happens automatically during model weight dequantization.\n\n## Fix\n\nA fix for this vulnerability was added here: https://github.com/vllm-project/vllm/pull/44971",
