CVE-2026-71227

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 kcapiaioreadall function can enter a non-terminating wait loop. This can lead to a persistent...
