Doc Text:
A flaw was found in the Intel Graphics Driver software installer. Due to incorrect default file permissions set by the installer, a local authenticated attacker could exploit the installation process during an active user session. Successful exploitation requires specific conditions and user interaction, which may allow the attacker to achieve privilege escalation on the local system.

Description OSIDB Bzimport 2026-11-10 19:41:06 UTC 
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.
