Summary
[none]
Details

In the Linux kernel, the following vulnerability has been resolved:

uiohvgeneric: Fix a memory leak in error handling paths

If 'vmbusestablishgpadl()' fails, the (recv|send)gpadl will not be updated and 'hvuio_cleanup()' in the error handling path will not be able to free the corresponding buffer.

In such a case, we need to free the buffer explicitly.
