CVE-2025-68814: CVE-2025-68814: güvenlik açığı
Açıklama (NVD)
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.
