Short explanation

An uncontrolled search path vulnerability in Intel(R) Graphics Driver software installers (CVE-2026-20798) may allow escalation of privilege via local access and user interaction [S0].

Why does it matter?

This flaw can enable an authenticated low-privileged adversary to execute code locally and impact system components [S0].

What should be done?

  • Follow the official Intel security advisory [S0]
  • Apply guidance provided in the vendor references [S0]

Show the technical text from the sources

Uncontrolled search path 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 local code execution. 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.
