+# Out-of-bounds memory access in `MemoryMappedFile::atomic_buffer()`
+
+`MemoryMappedFile::atomic_buffer()` performs unchecked pointer arithmetic
+without validating that the offset + length fits within the mapped file size.
+Passing an offset far beyond the file size causes a segmentation fault on
+subsequent buffer operations.
+
+This can be triggered through safe public APIs — `atomic_buffer()` is a safe
+method — with no `unsafe` required from the caller.
