{"id":"CVE-2026-71227","summary":"Libkcapi: infinite loop denial of service in libkcapi _kcapi_aio_read_all() due to unhandled io_getevents() timeout return","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":"2026-08-13T03:52:04.571428356Z","published":"2026-08-05T12:42:10.427Z","database_specific":{"cna_assigner":"redhat","cwe_ids":["CWE-835"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71227.json"},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-71227"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/71xxx/CVE-2026-71227.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-71227"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2462867"},{"type":"PACKAGE","url":"https://github.com/smuellerDD/libkcapi"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/smuellerdd/libkcapi","events":[{"introduced":"5ba1fbe1b5ff967c398e4dffab083d543809195c"},{"fixed":"df40ea48ecbf1afc6d3efa5494673fa73bd40826"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.12.0"},{"fixed":"1.5.1"}]}}],"versions":["v1.5.0","v1.4.0","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.5","v1.1.4","v1.1.3","v1.1.2","v1.1.1","v1.1.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.14.0","v0.13.0","v0.12.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/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"}]}
