CVE-2026-41476 Details
Description
Deskflow is a keyboard and mouse sharing app. Prior to 1.26.0.138, a remote memory-safety vulnerability in Deskflow's clipboard deserialization allows a connected peer to trigger an out-of-bounds read by sending a malformed clipboard update. The issue is in the implementation of src/lib/deskflow/IClipboard.cpp. This is reachable because ClipboardChunk::assemble() in src/lib/deskflow/ClipboardChunk.cpp validates only the outer clipboard transfer size. It does not validate the internal structure of the serialized clipboard blob, so malformed inner lengths reach IClipboard::unmarshall() unchanged. This vulnerability is fixed in 1.26.0.138.
A remote memory-safety vulnerability has been identified in Deskflow, a keyboard and mouse sharing application, prior to version 1.26.0.138. The issue arises in the clipboard deserialization process, where a connected peer can trigger an out-of-bounds read by sending a malformed clipboard update. This vulnerability is rooted in the improper validation of the internal structure of serialized clipboard data, allowing exploitation by crafting specific clipboard payloads.
Users should update Deskflow to version 1.26.0.138 or later.
