{"id":"USN-6540-1","summary":"bluez vulnerability","details":"It was discovered that BlueZ did not properly restrict non-bonded devices\nfrom injecting HID events into the input subsystem. This could allow a\nphysically proximate attacker to inject keystrokes and execute arbitrary\ncommands whilst the device is discoverable.\n","modified":"2026-06-25T13:32:25.745054429Z","published":"2023-12-07T04:07:20Z","related":["UBUNTU-CVE-2023-45866"],"upstream":["CVE-2023-45866","UBUNTU-CVE-2023-45866"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6540-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-45866"}],"affected":[{"package":{"name":"bluez","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/bluez?arch=source&distro=esm-infra%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.37-0ubuntu5.3+esm3"}]}],"versions":["5.35-0ubuntu2","5.36-0ubuntu1","5.37-0ubuntu5","5.37-0ubuntu5.1","5.37-0ubuntu5.3","5.37-0ubuntu5.3+esm1","5.37-0ubuntu5.3+esm2"],"ecosystem_specific":{"availability":"Available
