Python Vulnerability Enables Out-of-Bounds Write on Windows

A high-severity out-of-bounds write vulnerability (CVE-2026-3298) was disclosed in Python's asyncio.ProactorEventLoop on Windows: when using sock_recvfrom_into with the optional nbytes parameter, received data can exceed the preallocated buffer and overwrite adjacent memory, potentially causing crashes or arbitrary code execution; a fix has been submitted and Windows users should apply the updated Python release or avoid using sock_recvfrom_into with nbytes until patched.
