{"id":"ALPINE-CVE-2026-71227","details":"A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. By reusing an AIO-enabled handle after a prior completion error, the _kcapi_aio_read_all() function can enter a non-terminating wait loop. This can lead to a persistent denial of service, making the affected application or thread unresponsive.","modified":"2026-08-27T22:17:57.487604311Z","published":"2026-08-05T13:24:47.353Z","upstream":["CVE-2026-71227"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-71227"}],"affected":[{"package":{"name":"libkcapi","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/libkcapi?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.12.0"},{"fixed":"1.5.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-71227.json"}},{"package":{"name":"libkcapi","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libkcapi?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.12.0"},{"fixed":"1.5.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-71227.json"}},{"package":{"name":"libkcapi","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libkcapi?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.12.0"},{"fixed":"1.5.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-71227.json"}},{"package":{"name":"libkcapi","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/libkcapi?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0.12.0"},{"fixed":"1.5.1-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-71227.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
