In the Linux kernel, the following vulnerability has been resolved:
io_uring: Fix release of pinned pages when __io_uaddr_map fails Looking at
the error path of __io_uaddr_map, if we fail after pinning the pages for
any reasons, ret will be set to -EINVAL and the error handler won’t
properly release the pinned pages. I didn’t manage to trigger it without
forcing a failure, but it can happen in real life when memory is heavily
fragmented.
