🚨High - libkcapi One-shot AIO Use-After-Free Memory Corruption (CVE-2026-71226) libkcapi’s one-shot async I/O (AIO) path can return an error before all submitted AIO control blocks are drained. This leaves in-flight ops that later trigger kernel writes into caller-provided output buffers after they’ve been freed/reused, causing UAF-driven memory corruption and potential code execution. Non-AIO paths aren’t affected. 👉Affected: libkcapi / libkcapi-main; openshift/ose-rhel-coreos-8, openshift/ose-rhel-coreos-9
