{"id":"ALPINE-CVE-2026-15442","details":"In all builds that make use of (D)TLS, including default builds, there is a series of conditional states during the TLS shutdown which could lead to a heap-use-after free. If an application ended up getting a partial wolfSSL_read() which is sometimes caused by a small user buffer  passed in, then called wolfSSL_shutdown for a bidirectional close and attempted to wolfSSL_read() again while the peer continues trying to send data during the shutdown it would lead to a state where a potential heap-use-after free happened.","modified":"2026-11-03T06:33:01.449418871Z","published":"2026-09-27T10:16:56.893Z","upstream":["CVE-2026-15442"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-15442"}],"affected":[{"package":{"name":"wolfssl","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/wolfssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.4.0"},{"fixed":"5.9.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-15442.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
