{"id":"ALPINE-CVE-2026-39892","details":"cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7.","modified":"2026-04-24T17:34:19.731617Z","published":"2026-04-08T21:17:01.547Z","upstream":["CVE-2026-39892"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-39892"}],"affected":[{"package":{"name":"py3-cryptography","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/py3-cryptography?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"46.0.7-r0"}]}],"versions":["0.6.1-r0","0.8.2-r0","1.0.2-r0","1.3.1-r0","1.3.2-r0","1.4-r0","1.4-r1","1.4-r2","1.5.2-r0","1.5.2-r1","1.5.3-r0","1.7.2-r0","1.7.2-r1","1.8.1-r0","1.8.1-r1","1.9-r0","2.0.2-r0","2.0.3-r0","2.0.3-r1","2.1.3-r0","2.1.4-r0","2.1.4-r1","2.2.2-r0","2.3.1-r0","2.3.1-r1","2.4.2-r0","2.4.2-r1","2.4.2-r2","2.5-r0","2.6.1-r0","2.6.1-r1","2.7-r0","2.7-r1","2.8-r0","2.8-r1","2.9-r0","2.9.2-r0","3.2.1-r0","3.3-r0","3.3.1-r0","3.3.2-r0","3.3.2-r1","3.3.2-r2","3.3.2-r3","3.3.2-r4","3.4.8-r0","3.4.8-r1","37.0.4-r0","37.0.4-r1","37.0.4-r2","38.0.1-r0","38.0.2-r0","38.0.3-r0","38.0.3-r1","38.0.4-r0","39.0.0-r0","39.0.1-r0","39.0.2-r0","40.0.0-r0","40.0.1-r0","40.0.2-r0","40.0.2-r1","41.0.0-r0","41.0.1-r0","41.0.2-r0","41.0.2-r1","41.0.2-r2","41.0.3-r0","41.0.4-r0","41.0.5-r0","41.0.7-r0","42.0.5-r0","42.0.5-r1","42.0.7-r0","42.0.8-r0","43.0.0-r0","43.0.1-r0","43.0.3-r0","44.0.0-r0","44.0.1-r0","44.0.2-r0","44.0.3-r0","46.0.2-r0","46.0.3-r0","46.0.5-r0"],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-39892.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
