Service interruption via freed-memory access
Published Feb 19, 2026 · Updated Feb 19, 2026
Use-after-free in Tanium Cloud Workloads before 1.0.222 allows local users with Client Container access to interrupt the Enforce extension. The Enforce client extension accesses memory after it has been freed, but Tanium has not published the affected object or triggering code path. Exploitation requires low-privileged access inside a Tanium Client Container and a high-complexity trigger; the reported consequence is interruption of the Enforce extension, not data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
