  "description": "In the Linux kernel, the following vulnerability has been resolved:  f2fs: Require FMODE_WRITE for atomic write ioctls  The F2FS ioctls for starting and committing atomic writes check for inode_owner_or_capable(), but this does not give LSMs like SELinux or Landlock an opportunity to deny the write access - if the caller\u0027s FSUID matches the inode\u0027s UID, inode_owner_or_capable() immediately returns true.  There are scenarios where LSMs want to deny a process the ability to write particular files, even files that the FSUID of the process owns; but this can currently partially be bypassed using atomic write ioctls in two ways:   - F2FS_IOC_START_ATOMIC_REPLACE \u002B F2FS_IOC_COMMIT_ATOMIC_WRITE can    truncate an inode to size 0  - F2FS_IOC_START_ATOMIC_WRITE \u002B F2FS_IOC_ABORT_ATOMIC_WRITE can revert    changes another process concurrently made to a file  Fix it by requiring FMODE_WRITE for these operations, just like for F2FS_IOC_MOVE_RANGE. Since any legitimate caller should only be using these ioctls when intending to write into the file, that seems unlikely to break anything.",
