About this tag
The hybrid security inventory tag focuses on security issues that cross the boundaries of a Microsoft environment, particularly where Windows administration overlaps with Linux systems and hybrid infrastructure. The current discussion examines CVE-2026-52935, a Linux kernel vulnerability in the XFRM subsystem’s ESP-in-TCP path, and explains why it matters to Windows administrators even though it is not a Windows desktop flaw.
