Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Constructing slices from raw memory maps without validating that the length is within `isize::MAX` bounds can lead to undefined behavior, particularly on 32-bit targets.
Memory Safety: Exposing memory advising operations like `unchecked_advise_range` as safe Rust functions allows arbitrary, unvalidated memory offset operations that can trigger undefined behavior if callers pass invalid ranges.
Integer Overflow: Calculating file lengths on 32-bit systems can result in integer truncation or overflows during mapping option parsing, causing incorrect memory boundaries to be mapped.
