# CVE-2025-68814

## Summary

- **CVE ID:** CVE-2025-68814
- **Severity:** UNKNOWN
- **CVSS Score:** 1.01
- **CWE:** N/A
- **Published:** Jan 13, 2026
- **Last Modified:** Sep 17, 2026

## Description

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

io_uring: fix filename leak in __io_openat_prep()

 __io_openat_prep() allocates a struct filename using getname(). However,
for the condition of the file being installed in the fixed file table as
well as having O_CLOEXEC flag set, the function returns early. At that
point, the request doesn't have REQ_F_NEED_CLEANUP flag set. Due to this,
the memory for the newly allocated struct filename is not cleaned up,
causing a memory leak.

Fix this by setting the REQ_F_NEED_CLEANUP for the request just after the
successful getname() call, so that when the request is torn down, the
filename will be cleaned up, along with other resources needing cleanup.
