**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to insufficient input validation in the io uring component of the Linux kernel. Specifically, the function ` io uaddr map()` in io uring/io uring.c does not properly handle errors, leading to a potential denial of service. When memory is heavily fragmented, the error handler may not properly release pinned pages, causing issues. The vulnerability can be triggered in real-life scenarios, but it requires specific conditions. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
