Windows Kernel Information Disclosure in CPU Memory Access
An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to try to compromise the affected system further.
FAQ
What type of information could be disclosed by this vulnerability?
The type of information that could be disclosed if an attacker successfully exploited this vulnerability is the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.
Where can I find information regarding other speculative side-channel execution vulnerabilities?
For information on Microsoft guidance for the Spectre Variant 1 speculative execution side channel vulnerability, see ADV180002 | Guidance to mitigate speculative execution side-channel vulnerabilities.
