CVE-2026-33444Network attack vector

Non-persistent server interruption via tunnel memory error

Published Jul 15, 2026 · Updated Jul 15, 2026

Memory management error in Absolute Secure Access Server before 14.56 allows remote attackers to interrupt the server via tunnel traffic. Absolute has not disclosed the affected routine or the incorrect memory operation performed while the server processes tunnel-protocol input. Exploitation requires intimate protocol knowledge and total control of the tunnel exchange; the resulting denial of service is non-persistent.
