{"id":"DEBIAN-CVE-2026-41054","details":"In `src/havegecmd.c`, the `socket_handler` function performs a credential check on the abstract UNIX socket (`\\0/sys/entropy/haveged`). However, while it detects if the connecting user is not root (`cred.uid != 0`) and prepares a negative acknowledgement (`ASCII_NAK`), it **fails to stop execution**. The code proceeds to the `switch` statement, allowing any local unprivileged user to execute privileged commands such as `MAGIC_CHROOT`.","modified":"2026-10-01T03:03:12.028983348Z","published":"2026-05-20T10:16:26.990Z","upstream":["CVE-2026-41054"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-41054"}],"affected":[{"package":{"name":"haveged","ecosystem":"Debian:12","purl":"pkg:deb/debian/haveged?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.14-1+deb12u1"}]}],"versions":["1.9.14-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41054.json"}},{"package":{"name":"haveged","ecosystem":"Debian:13","purl":"pkg:deb/debian/haveged?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.19-12+deb13u1"}]}],"versions":["1.9.19-12"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41054.json"}},{"package":{"name":"haveged","ecosystem":"Debian:14","purl":"pkg:deb/debian/haveged?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.9.21-1"}]}],"versions":["1.9.19-12","1.9.19-13","1.9.19-14","1.9.19-15","1.9.20-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-41054.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
