Windows Python Users Warned of High-Severity “asyncio” Memory Flaw

A high-severity vulnerability (CVE-2026-3298, CVSS 8.8) was discovered in Python's asyncio ProactorEventLoop on Windows: the sock_recvfrom_into() method lacks a boundary check for the provided buffer, enabling out-of-bounds writes that can lead to application crashes or remote code execution. Administrators and developers should identify affected Windows Python installations and upgrade to Python 3.15.0 or apply available security/backport fixes.
