Official Description
A vulnerability in the client isolation mechanism may allow an attacker to bypass Layer 2 (L2) communication restrictions between clients and redirect traffic at Layer 3 (L3). In addition to bypassing policy enforcement, successful exploitation - when combined with a port-stealing attack - may enable a bi-directional Machine-in-the-Middle (MitM) attack.
Technical Analysis
CVE-2026-23811 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
