libkcapi: Infinite loop denial of service in libkcapi _kcapi_aio_read_all() due to unhandled io_getevents() timeout return

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...

RLSA-2026:67267 Moderate: libkcapi security, bug fix, and enhancement update

libkcapi allows user-space to access the Linux kernel crypto API. This library uses the netlink interface and exports easy to use APIs so that a developer does not need to consider the low-level netlink interface handling. The library does not implement any cipher algorithms. All consumer request...

CVE-2026-71227

CVE-2026-71227 affects libkcapi. The issue arises in the AIO path where reusing an AIO-enabled handle after a prior completion error can cause _kcapi_aio_read_all() to enter a non-terminating wait loop, leading to persistent denial of service and unresponsiveness of the affected application or th...

[oss-security] CVE-2014-0206 -- Linux kernel: kernel memory disclosure in io_getevents()

A kernel memory disclosure was introduced in aioreadeventsring in v3.10 by commit a31ad380bed817aa25f8830ad23e1a0480fef797. The changes made to aioreadeventsring failed to correctly limit the index into ctx-ringpages, allowing an attacker to cause the subsequent kmap of an arbitrary page with a...
