Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

An elevation of privilege vulnerability exists when the Windows fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code. 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 to take control of an affected system. The update addresses the vulnerability by correcting how the Windows handles objects in memory.
