scsi: ufs: debugfs: Reserve space for a string terminator
In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: debugfs: Reserve space for a string terminator ufs_saved_err_write() copies user input into a zero-initialized stack buffer and passes it to kstrtoint(). A write that fills the entire buffer overwrites its only terminator. Reject an input whose length leaves no room for the trailing NUL.
