{"id":"ALPINE-CVE-2026-123158","details":"sshd in OpenSSH before 10.6p2 on Linux, when musl libc is used without PAM, lacks a workaround for a password authentication bypass (related to misinterpretation of whether a string is intended to be a password hash). For some configurations of accounts, any password between 256 and 1024 characters succeeds. An example of a platform using musl libc without PAM is Alpine Linux.","modified":"2026-11-06T11:30:02.987427550Z","published":"2026-11-05T16:17:47.110Z","upstream":["CVE-2026-123158"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-123158"}],"affected":[{"package":{"name":"openssh","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.0_p1-r6"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.1_p1-r7"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.3_p2-r4"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.6_p1-r3"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.7_p1-r6"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"9.9_p2-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.0_p1-r11"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.2_p1-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}},{"package":{"name":"openssh","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/openssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"10.3_p1-r2"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-123158.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
