Vulnerability from fkie_nvd - Published: 2025-10-07 16:15 - Updated: 2026-06-17 05:23
Severity
Summary
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.
