About this tag
CVE-2026-31552 is a Linux kernel vulnerability in the wlcore Wi-Fi driver where returning -EAGAIN instead of -ENOMEM when packet headroom cannot be expanded causes an infinite retry loop, leading to a CPU soft lockup. This high-severity availability issue does not directly affect Windows, but it is relevant to WindowsForum readers using WSL, Azure workloads, or embedded devices that rely on the Linux kernel. The flaw highlights how subtle kernel security bugs can cause denial-of-service conditions without memory corruption or remote code execution.

    CVE-2026-31552: wlcore Wi‑Fi driver -EAGAIN vs -ENOMEM infinite retry CPU soft lockup

    CVE-2026-31552 is a reminder that kernel security failures do not always arrive as dramatic memory corruption bugs or remote code execution chains. This Linux Wi-Fi driver flaw turns on a deceptively small change: returning -EAGAIN instead of -ENOMEM when the wlcore driver cannot expand packet...
