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.
