Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Cyfs base, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The function `ChunkId::new` creates a misaligned pointer by casting mutable pointer of `u8` slice which has alignment 1 to the mutable pointer of `u32` which has alignment 4, and dereference the misaligned pointer leading UB, which should not be allowed in safe function.
