CVE-2025-55696

Name of the Vulnerable Software and Affected Versions Windows (affected versions not specified)

Description A time-of-check time-of-use (TOCTOU) race condition exists in the NtQueryInformationToken function within ntifs.h. This condition allows a locally authorized attacker to elevate privileges. The issue involves a timing vulnerability where the system state changes between the time a check is performed and the time the result of that check is used. This can lead to unintended consequences, such as granting higher privileges than intended.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
