+# `EbpfVm::invoke_function` performs out-of-bounds pointer arithmetic
+
+Affected versions of `solana_rbpf` expose the safe method
+`EbpfVm::invoke_function`. This method computes an obfuscated VM pointer by
+casting `self` to `*mut u64` and applying a randomized offset derived from
+`get_runtime_environment_key()`.
+
+The resulting pointer arithmetic is performed with `ptr::offset`, which
+requires the computed pointer to remain within the same allocation. In practice,
+the randomized offset can move the pointer far outside the allocation
+containing the `EbpfVm`, causing undefined behavior before the supplied builtin
+function is invoked.
+
+## Unmaintained
+
+The upstream `solana_rbpf` repository is archived, and no patched version of
+this crate is currently available.
+
+Users should migrate to the maintained [`solana-sbpf`](https://crates.io/crates/solana-sbpf)
+crate. The issue has been fixed there in
+[`anza-xyz/sbpf#151`](https://github.com/anza-xyz/sbpf/pull/151).
