CVE-2026-71227
5.1 · MEDIUMOverview
CVE-2026-71227 is a medium-severity vulnerability affecting redhat hardened_images. It was published on August 5, 2026 and has a CVSS 3.1 base score of 5.1 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.1, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from redhat. Update hardened_images to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
