Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> io_uring: Fix release of pinned pages when __io_uaddr_map fails<br /> <br /> Looking at the error path of __io_uaddr_map, if we fail after pinning<br /> the pages for any reasons, ret will be set to -EINVAL and the error<br /> handler won&amp;#39;t properly release the pinned pages.<br /> <br /> I didn&amp;#39;t manage to trigger it without forcing a failure, but it can<br /> happen in real life when memory is heavily fragmented.
