Name of the Vulnerable Software and Affected Versions: LibAFL versions prior to 0.11.2

Description: The issue arises from the misuse of the slice::from raw parts mut API, where a pointer is misaligned due to a direct cast from u8 to u16 raw pointer, leading to unsound behavior. The problem is resolved by utilizing align offset to ensure memory address alignment for u16 to 2 bytes.

Recommendations: For versions prior to 0.11.2, update to version 0.11.2 or later to resolve the issue. As a temporary workaround, consider using align offset to align memory addresses to 2 bytes for u16 to minimize the risk of exploitation.
