Vulnerability from fkie_nvd - Published: 2026-07-25 10:17 - Updated: 2026-09-03 16:03
Severity
Summary
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.
