What is CVE-2026-20426?

This vulnerability arises due to a missing bounds check in the display component, enabling potential local escalation of privileges for attackers who have already gained system-level access. Notably, user interaction is unnecessary, making this flaw all the more critical for security. Affected systems should be patched promptly to mitigate associated risks.
