What this means

Intel Graphics Driver software installers have incorrect default permissions, potentially allowing an unprivileged attacker with local access and user interaction to escalate privileges, impacting system confidentiality, integrity, and availability. The affected versions are not specified. High complexity and authenticated user access are required.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Attack conditions

This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active user interaction.

Original source description

Read the full publisher description

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.
