An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.
The update addresses this vulnerability by correcting how the Windows kernel-mode driver handles objects in memory.

[HIGH] Microsoft Patch Tuesday, May 2020 Edition
Microsoft today issued software updates to plug at least 111 security holes in Windows and Windows-based programs. None of the vulnerabilities were labeled as being publicly exploited or detailed prior to today, but as always if you’re running Windows on any of your machines it’s time once again to prepare to get your patches on.
May marks the third month in a row that Microsoft has pushed out fixes for more than 110 security flaws in its operating system and related software. At least 16 of the bugs are labeled “Critical,” meaning ne’er-do-wells can exploit them to install malware or seize remote control over vulnerable systems with little or no help from users.
But focusing solely on Microsoft’s severity ratings may obscure the seriousness of the flaws being addressed this month. Todd

But focusing solely on Microsoft’s severity ratings may obscure the seriousness of the flaws being addressed this month. Todd Schell, senior product manager at security vendor Ivanti, notes that if one looks at the “exploitability assessment” tied to each patch — i.e., how likely Microsoft considers each can and will be exploited for nefarious purposes — it makes sense to pay just as much attention to the vulnerabilities Microsoft has labeled with the lesser seve
