ebpf co-re

The ebpf co-re tag on WindowsForum.com covers discussions about BPF CO-RE (Compile Once, Run Everywhere), a feature of the Linux kernel that enables portable eBPF programs. Content under this tag includes security vulnerabilities such as CVE-2026-45839, a BPF CO-RE parsing bug that allows privileged users with CAP_BPF to crash kernels with vmlinux BTF support. While this is a Linux kernel issue, it is relevant to Windows users because Linux runs within Windows environments via WSL, containers, developer workstations, CI runners, and cloud hosts. The tag highlights how modern kernel attack surfaces extend beyond traditional drivers and syscalls into developer-focused features like eBPF and CO-RE.
