Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Out-of-bounds Write: Negative or improperly cast offsets allowed operations to write past or before the allocated buffer boundary. The fix enforced consistent unsigned integer coercion using '>>> 0' to prevent offset manipulation from bypassing bounds checks.
Information Disclosure: Using 'noAssert' flags during Buffer operations allowed reads and writes to bypass bounds checks, exposing the raw parent buffer shared memory pool beyond the allocated slice boundaries and leaking sensitive data.
