  "details": "In the Linux kernel, the following vulnerability has been resolved:  netfilter: ebtables: terminate table name before find_table_lock()  update_counters() and compat_update_counters() forward a user-supplied 32-byte table name to find_table_lock() without NUL-terminating it. On a lookup miss, find_inlist_lock() calls try_then_request_module(..., \"%s%s\", \"ebtable_\", name), and vsnprintf() reads past the name field and the stack object until it hits a zero byte.
