BPF is in a unique position in terms of security. It runs in a privileged
context, within the kernel, and can have access to many sensitive details of the
kernel’s operation. At the same time, unlike kernel modules, BPF programs aren’t signed.
Additionally, the mechanisms behind BPF present challenges to implementing
signing or other security features. Three nearly back-to-back sessions at the
2024
Linux Storage,
Filesystem, Memory Management, and BPF Summit
addressed some of the potential security problems.
