Is there a public PoC exploit available for EUVD-2026-43247?

Yes, a public proof-of-concept exploit is available for EUVD-2026-43247. Prioritise patching immediately. EPSS: 0.2%.

How to fix or mitigate EUVD-2026-43247?

24 hours: Audit all endpoints running SecureAge CatchPulse 10.9.3 or earlier; restrict local login access to essential personnel only and enforce strong authentication. 7 days: Isolate or network-segment critical endpoints running vulnerable versions; enable kernel-level monitoring and advanced driver behavior logging on affected systems. 30 days: Monitor SecureAge vendor advisories and security bulletins for patch availability; if patch timeline exceeds organizational risk tolerance, develop and execute migration plan to alternative endpoint protection vendor.

DescriptionCVE.org

A security vulnerability has been detected in SecureAge CatchPulse up to 10.9.3. The affected element is an unknown function in the library saappctl.sys of the component Driver. Such manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure.

AnalysisAI

Local privilege escalation in SecureAge CatchPulse endpoint protection (versions up to and including 10.9.3) stems from a heap-based buffer overflow in the kernel driver saappctl.sys, where an authenticated local user can corrupt kernel heap memory to gain code execution at ring 0. Publicly available exploit code exists (demonstrated in a YouTube proof-of-concept), but there is no public exploit identified as being used in active attacks and the issue is not on CISA KEV. …
