Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
Description
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.
