{"id":"DEBIAN-CVE-2026-115485","details":"A flaw was found in the iscsiuio component of open-iscsi. The DHCPv6 option parser calls strlen() on raw network data without ensuring a NUL terminator is present, causing it to read past the buffer into heap memory. This can result in a daemon crash, a 1-byte heap overwrite, or corruption of the iSCSI initiator name. An attacker on the same network segment can trigger this by sending a crafted DHCPv6 Advertise message.","modified":"2026-10-24T09:47:27.060499730Z","published":"2026-10-23T01:16:53.817Z","upstream":["CVE-2026-115485"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-115485"}],"affected":[{"package":{"name":"open-iscsi","ecosystem":"Debian:12","purl":"pkg:deb/debian/open-iscsi?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.10-1","2.1.10-2","2.1.10-3","2.1.11-1","2.1.11-2","2.1.11-3","2.1.11-4","2.1.11-5","2.1.11-6","2.1.12-1","2.1.12-2","2.1.13-1","2.1.8-1","2.1.8-1+deb12u1","2.1.8-2","2.1.9-1","2.1.9-2","2.1.9-3","2.1.9-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115485.json"}},{"package":{"name":"open-iscsi","ecosystem":"Debian:13","purl":"pkg:deb/debian/open-iscsi?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.11-1","2.1.11-1+deb13u1","2.1.11-1+deb13u2","2.1.11-2","2.1.11-3","2.1.11-4","2.1.11-5","2.1.11-6","2.1.12-1","2.1.12-2","2.1.13-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115485.json"}},{"package":{"name":"open-iscsi","ecosystem":"Debian:14","purl":"pkg:deb/debian/open-iscsi?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.11-1","2.1.11-2","2.1.11-3","2.1.11-4","2.1.11-5","2.1.11-6","2.1.12-1","2.1.12-2","2.1.13-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-115485.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
