| Package Name | Ecosystem | Vulnerable Versions | First Patched Version |
|---|---|---|---|
| ckb | rust | <= 0.31.0 | 0.31.1 |
The vulnerability stems from unsafe pointer casts from byte arrays to native integer pointers (u32/u64/u128) followed by immediate dereferencing. This violates Rust's alignment requirements, creating undefined behavior. The commit diff shows these patterns were replaced with safe byte array copying using from_le_bytes/from_be_bytes, confirming the original implementations were vulnerable. The affected functions are clearly identified in protocol message decoding and primitive type conversion implementations where raw pointer manipulation occurred.
