  2. Multiple vulnerabilities related to an improper handling of memory addresses can be exploited locally via a specially designed application to obtain sensitive information;
  3. Multiple vulnerabilities related to an incorrect handling of objects in memory done by the Windows kernel-mode driver can be exploited locally via a specially designed application to gain privileges;
  4. Multiple vulnerabilities related to an improper initialization of objects in memory can be exploited locally via a specialy designed application to obtain sensitive information;
  5. An improper handling of objects in memory related to proper enforcement of VTLs (virtual trust levels) can be exploited locally via a specially designed application to gain privileges.

Technical details

Vulnerabilities (2) occur in case the Windows kernel fails to initialize a memory adress in a proper way and can cause security bypass called KASLR (Kernel Address Space Layout Randomization) bypass.
