kernel backport

About this tag
The kernel backport tag on WindowsForum.com covers discussions about applying security fixes and regression patches from newer Linux kernel versions to older stable or long-term support (LTS) kernels. A recent thread details the backport of a fix for CVE-2025-40305, a 9P transport scheduling bug that could cause write path hangs. The solution replaces a narrow EPOLLOUT-only check with a full poll multiplex invocation to reliably wake the receive worker on EPOLLIN conditions. Such backports are critical for maintaining system stability and security in enterprise and virtualized environments where older kernels remain in use.
