# Intel Graphics Driver installers: default permissions allow local privilege escalation

Link for people: https://infrastack.ai/live/CVE-2026-20880 (this .md is for agents)

Some Intel Graphics Driver software installers ship with incorrect default file permissions. A local user with an account can escalate privileges to gain full control of the system.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Incorrect default permissions for some Intel(R) Graphics Driver software installers within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
