Technical description
In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix leak when pinning ubuf pages
When pin_user_pages_fast() returns fewer pages than requested, the pages
that were successfully pinned are not released, leading to a leak.
Fix this by unpinning any partially pinned pages before returning failure.
