{"id":"ALPINE-CVE-2025-5351","details":"A flaw was found in the key export functionality of libssh. The issue occurs in the internal function responsible for converting cryptographic keys into serialized formats. During error handling, a memory structure is freed but not cleared, leading to a potential double free issue if an additional failure occurs later in the function. This condition may result in heap corruption or application instability in low-memory scenarios, posing a risk to system reliability where key export operations are performed.","modified":"2026-11-03T06:33:00.699297423Z","published":"2025-07-04T09:15:37.100Z","upstream":["CVE-2025-5351"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2025-5351"}],"affected":[{"package":{"name":"libssh","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.10.0"},{"fixed":"0.11.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-5351.json"}},{"package":{"name":"libssh","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.10.0"},{"fixed":"0.11.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-5351.json"}},{"package":{"name":"libssh","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/libssh?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.10.0"},{"fixed":"0.11.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2025-5351.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
