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...

python: Unbounded memory buffering in SelectorSocketTransport.writelines()

A flaw was found in Python. In certain configurations, the asyncio.SelectorSocketTransport.writelines method fails to signal the protocol to clear the write buffer when it approaches capacity. Because of this, protocols would not periodically drain the write buffer, potentially leading to a denia...
