CVE-2026-53923

CVE-2026-53923 affects vLLM GGUF dequantize kernels. Root cause: integer truncation due to using int for the element count parameter, causing m*n (potentially > INT_MAX) to be truncated when passing to CUDA kernels, leading to unfilled output tensor memory that may retain data from previous in...
