What is CVE-2023-53838?

A vulnerability exists in the Linux kernel's f2fs file system, where a race condition during atomic write operations can lead to denial of service or corruption of file data. The issue has been addressed by implementing inode locking and enhancing the reusability of copy-on-write (COW) inodes throughout the atomic file inode's lifecycle. This fix strengthens the overall stability and reliability of file operations within affected versions of the Linux kernel.
