Allowing User-mode Code to Access Kernel Memory

Allowing User-mode Code to Access Kernel Memory One of the most important principles of the kernel/user division that modern operating systems enforce is that user mode is not allowed to directly access kernel mode memory. This is necessary to enforce system stability, such as to prevent a buggy...

Kaspersky Antivirus multiple vulnerabilities

Unsafe kernel mode components implementation leads to Denial of Service and potentially to privilege elevation. Most serious problem is user mode code can access kernel memory...

Improper Validation of User-mode Pointers

Improper Validation of User-mode Pointers Many of the hooks that KAV installs and even the custom system services suffer from flaws that are detrimental to the operation of the system. For instance, KAV's modified NtOpenProcess attempts to determine if a user address is valid by comparing it to t...
