Frequently Asked Questions

1

What conditions are required to trigger the invalid storage access?

A cgroup BPF program with local storage must be attached in multi-attach mode, then replaced using BPF_F_REPLACE in multi-attach mode. The replacement must fail after storage has been overwritten but before attachment completes, and a subsequent program must then be attached in multi-attach mode.

2

What happens after the failed replacement?

The previously active program can retain dangling pointers to storage that was freed during cleanup. If that program later executes and calls bpf_get_local_storage, it can perform an invalid memory access.

3

Are configuration flags also affected by the failed attach cleanup?

Yes. The original program-link flags and the cgroup attachment-type flags may remain unrestored after the failed replacement attempt.
