Detailsinfo

A vulnerability was found in Intel NPU Driver software installers. It has been declared as critical. Affected by this vulnerability is some unknown processing. The manipulation with an unknown input leads to a default permission vulnerability. The CWE definition for the vulnerability is CWE-276. During installation, installed file permissions are set to allow anyone to modify those files. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Incorrect default permissions for some Intel(R) NPU Driver software installers before version 32.0.100.4511 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.
