Summary
scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()
Details

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: iscsi: Fix buffer overflow in liotargetnaclinfoshow()

The function liotargetnaclinfoshow() uses sprintf() in a loop to print details for every iSCSI connection in a session without checking for the buffer length. With enough iSCSI connections it's possible to overflow the buffer provided by configfs and corrupt the memory.

This patch replaces sprintf() with sysfsemitat() that checks for buffer boundries.
