CVE-2026-69779

A time-of-check time-of-use (TOCTOU) race condition vulnerability in Windows Win32K enables authorized attackers to elevate their privileges locally, potentially allowing them to execute arbitrary code with elevated permissions. Organizations using affected Windows systems should prioritize patching this vulnerability to mitigate the risk of unauthorized access and potential system compromise. This is particularly critical for environments where users have elevated privileges or where sensitive data is handled.
