{"id":"DEBIAN-CVE-2026-2100","details":"A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states.","modified":"2026-09-29T08:47:27.505651261Z","published":"2026-03-26T21:17:04.247Z","upstream":["CVE-2026-2100"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-2100"}],"affected":[{"package":{"name":"p11-kit","ecosystem":"Debian:14","purl":"pkg:deb/debian/p11-kit?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.26.2-2"}]}],"versions":["0.25.10-1","0.25.5-3","0.25.9-1","0.25.9-2","0.26.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-2100.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
