{"id":"UBUNTU-CVE-2026-35094","details":"A flaw was found in libinput. An attacker capable of deploying a Lua plugin file in specific system directories can exploit a dangling pointer vulnerability. This occurs when a garbage collection cleanup function is called, leaving a pointer that can then be printed to system logs. This could potentially expose sensitive data if the memory location is re-used, leading to information disclosure. For this exploit to work, Lua plugins must be enabled in libinput and loaded by the compositor.","modified":"2026-06-05T23:45:15.927231847Z","published":"2026-04-01T14:16:00Z","withdrawn":"2026-06-05T21:54:40Z","upstream":["CVE-2026-35094"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35094"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35094"}],"affected":[{"package":{"name":"libinput","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libinput?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.28.1-1build1","1.28.1-1ubuntu2","1.30.0-1","1.30.1-1","1.31.0-1","1.31.0-1ubuntu0.1","1.31.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libinput-bin","binary_version":"1.31.1-1"},{"binary_version":"1.31.1-1","binary_name":"libinput-tools"},{"binary_version":"1.31.1-1","binary_name":"libinput10"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35094.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
