The network-statistics interface in the kernel in Apple iOS before 8 and Apple TV before 7 does not properly initialize memory, which allows attackers to obtain sensitive memory-content and memory-layout information via a crafted application, a different vulnerability than CVE-2014-4419, CVE-2014-4420, and CVE-2014-4421.


The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.

Potential Mitigations

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable’s type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
