In the Linux kernel, the following vulnerability has been resolved: usb: cdnsp: fix stream context array leak in cdnsp_alloc_stream_info() cdnsp_alloc_stream_info() allocates stream_info->stream_ctx_array with cdnsp_alloc_stream_ctx(). If a later stream ring allocation or stream mapping update fails, the error path frees the allocated stream rings and stream_rings array, but leaves stream_ctx_array allocated. Free the stream context array before falling through to the stream_rings cleanup path.

A flaw was found in the Linux kernel's USB cdnsp driver. The `cdnsp_alloc_stream_info()` function allocates a stream context array but fails to free it if subsequent allocations or updates fail. This memory leak could lead to a denial of service due to resource exhaustion.
