In any case, it's recommended to drop a file in sshd_config.d instead of editing sshd_config (bsc#1221063).\n- Add a patch to fix a regression introduced in 9.6 that makes X11 forwarding very slow (bsc#1229449).\n- Drop keycat binary that is not supported, except of the code that is used by other SELinux patches (bsc#1229072).\n- Fix RFC4256 implementation that keyboard-interactive authentication method can send instructions and sshd shows them to users (bsc#1229010).\n- Add attempts to mitigate instances of secrets lingering in memory after a session exits (bsc#1186673, bsc#1213004, bsc#1213008).\n- Remove empty line at the end of sshd-sle.pamd (bsc#1227456)","dates":{"published":"2025-03-25T09:02:20.000Z","modified":"2026-03-23T04:50:04.239Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"openssh&distro=SUSE Linux Micro 6.0","name":"openssh","label":"openssh&distro=SUSE Linux Micro 6.0","ecosystem":"SUSE Linux Enterprise","cpePart":null,"purl":"pkg:rpm/suse/openssh&distro=SUSE Linux Micro 6.0","purlType":"rpm","versions":[{"text":"< 9.6p1-3.1","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 9.6p1-3.1","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://www.suse.com/support/update/announcement/2025/suse-su-202520160-1/","label":"www.suse.com/support/update/announcement/2025/suse-su-202520160-1/","hostname":"www.suse.com","tags":["Advisory"]},{"url":"https://bugzilla.suse.com/1186673","label":"bugzilla.suse.com/1186673","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1213004","label":"bugzilla.suse.com/1213004","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1213008","label":"bugzilla.suse.com/1213008","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1221063","label":"bugzilla.suse.com/1221063","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1221928","label":"bugzilla.suse.com/1221928","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1222840","label":"bugzilla.suse.com/1222840","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1225904","label":"bugzilla.suse.com/1225904","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1227456","label":"bugzilla.suse.com/1227456","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1229010","label":"bugzilla.suse.com/1229010","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1229072","label":"bugzilla.suse.com/1229072","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1229449","label":"bugzilla.suse.com/1229449","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1236826","label":"bugzilla.suse.com/1236826","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1237040","label":"bugzilla.suse.com/1237040","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://bugzilla.suse.com/1237041","label":"bugzilla.suse.com/1237041","hostname":"bugzilla.suse.com","tags":["REPORT"]},{"url":"https://www.suse.com/security/cve/CVE-2025-26465","label":"www.suse.com/security/cve/CVE-2025-26465","hostname":"www.suse.com","tags":["WEB"]},{"url":"https://www.suse.com/security/cve/CVE-2025-26466","label":"www.suse.com/security/cve/CVE-2025-26466","hostname":"www.suse.com","tags":["WEB"]}],"lineage":{"upstream":["CVE-2025-26465","CVE-2025-26466"],"downstream":[],"duplicates":[],"related":["CVE-2025-26465","CVE-2025-26466"]},"timeline":[{"kind":"published","date":"2025-03-25T09:02:20.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-03-23T04:50:04.239Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-22T15:21:00.729Z","stale":false,"partial":false}}
