In the Linux kernel, the following vulnerability has been resolved: usb: host: xhci: Fix potential memory leak in xhci_alloc_stream_info() xhci_alloc_stream_info() allocates stream context array for stream_info ->stream_ctx_array with xhci_alloc_stream_ctx(). When some error occurs, stream_info->stream_ctx_array is not released, which will lead to a memory leak. We can fix it by releasing the stream_info->stream_ctx_array with xhci_free_stream_ctx() on the error path to avoid the potential memory leak.

Are you affected?

Enter the version you run. The result uses only the ranges stored on this record.
