{"id":"DEBIAN-CVE-2026-65976","details":"Deskflow is a keyboard and mouse sharing app. From 1.17.0 until continuous build 1.26.0.300, a connected peer can send repeated DCLP DataChunk messages to ClipboardChunk::assemble() in src/lib/deskflow/ClipboardChunk.cpp, causing the server path in src/lib/server/ClientProxy1_6.cpp or client path in src/lib/client/ServerProxy.cpp to append data beyond the DataStart declared size and configured clipboard limit before DataEnd validation, exhausting receiver memory. This issue is fixed in continuous build 1.26.0.300.","modified":"2026-09-10T08:47:28.617192361Z","published":"2026-08-17T21:16:47.027Z","upstream":["CVE-2026-65976"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-65976"}],"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-2026-65976.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-4"}]}],"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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-65976.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
