            Bug ID: 196533
           Summary: kernel stack infoleaks
           Product: Networking
           Version: 2.5
    Kernel Version: 4.12.2
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
          Assignee: stephen@...workplumber.org
          Reporter: sohu0106@....com
        Regression: No

bug in net/irda/af_irda.c  


Sometimes irda_getsockopt() doesn't initialize all members of list field of
irda_device_list struct.  This structure is then copied to
userland.  It leads to leaking of contents of kernel stack memory.  We have to
initialize them to zero , or it will allows local users to obtain potentially
sensitive information from kernel stack memory by reading a copy of this
structure
