Solutions

1. Ensure byte offsets used for diagnostics fall within the source text length.
2. Guard location conversions with checked arithmetic when offsets come from untrusted input.

Example fix

let offset = TextSize::try_from(u64_value).map_err(|_| io::Error::new(ErrorKind::InvalidInput, "integer overflow"))?;
