Last modified
CVE-2026-71227 is a medium-severity vulnerability rated 5.1/10 on the CVSS scale. A flaw was found in libkcapi. A local attacker can influence an application that uses the Asynchronous Input/Output (AIO) interface. EPSS estimates a 0.11% chance of exploitation in the next 30 days.
Description
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.
