CVE-2025-59596

Client crash via improperly validated network packets

Published Nov 4, 2025 · Updated Nov 4, 2025

Improper input validation in Absolute Secure Access Windows clients 12.0 through 14.10 allows attackers to crash the client via crafted packets. Absolute has not disclosed which packet field or client routine fails to validate the crafted network input before the crash. Exploitation requires an active local networking policy and adjacent-network reachability, and the reported consequence is a client-system crash.
