CVE-2026-41952

Local privilege escalation

Published Apr 29, 2026 · Updated Apr 29, 2026

Local privilege escalation in Acronis DeviceLock DLP and Cyber Protect Cloud Agent on Windows allows local users to gain elevated privileges. Acronis maps the defect to a write-what-where condition, but has not disclosed the affected component or the specific unchecked input and memory write. A low-privileged local account is required; successful exploitation crosses a Windows privilege boundary and can fully compromise the host.
