{"id":"DEBIAN-CVE-2026-41476","details":"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.","modified":"2026-09-14T17:03:33.227552679Z","published":"2026-04-24T20:16:28.207Z","upstream":["CVE-2026-41476"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41476"}],"affected":[{"package":{"name":"deskflow","ecosystem":"Debian:13","purl":"pkg:deb/debian/deskflow?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.22.0+dfsg-7","1.23.0+dfsg-1","1.23.0+dfsg-2","1.24.0+dfsg-1","1.24.0+dfsg-2","1.25.0+dfsg-1","1.25.0+dfsg-2","1.25.0+dfsg-3","1.26.0+dfsg-1","1.26.0+dfsg-2","1.26.0+dfsg-3","1.26.0+dfsg-4","1.26.0+dfsg-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41476.json"}},{"package":{"name":"deskflow","ecosystem":"Debian:14","purl":"pkg:deb/debian/deskflow?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.26.0+dfsg-2"}]}],"versions":["1.22.0+dfsg-7","1.23.0+dfsg-1","1.23.0+dfsg-2","1.24.0+dfsg-1","1.24.0+dfsg-2","1.25.0+dfsg-1","1.25.0+dfsg-2","1.25.0+dfsg-3","1.26.0+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41476.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
