Official Description
A flaw has been found in WAYOS FBM-220G 24.10.19. This affects the function sub_40F820 of the file rc.

The vendor was contacted early about this disclosure but did not respond in any way.
Technical Analysis
CVE-2026-2548 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
