{"id":"DEBIAN-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":"2026-09-25T04:00:06.831624806Z","published":"2026-08-05T13:24:47.353Z","upstream":["CVE-2026-71227"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-71227"}],"affected":[{"package":{"name":"libkcapi","ecosystem":"Debian:12","purl":"pkg:deb/debian/libkcapi?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.0-1","1.4.0-2","1.5.1-1","1.5.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-71227.json"}},{"package":{"name":"libkcapi","ecosystem":"Debian:13","purl":"pkg:deb/debian/libkcapi?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.0-1","1.4.0-2","1.5.1-1","1.5.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-71227.json"}},{"package":{"name":"libkcapi","ecosystem":"Debian:14","purl":"pkg:deb/debian/libkcapi?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.5.1-1"}]}],"versions":["1.4.0-1","1.4.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-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"}]}
