Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Buffer Overflow: An integer overflow during capacity calculation inside the allocator can lead to under-allocating memory, resulting in subsequent out-of-bounds writes when copying elements. This risk highlights the necessity of strict overflow checks when sizing memory buffers.
Memory Corruption: Trusting size hints or behavior from arbitrary, non-unsafe Iterator implementations can lead to mismatches between allocated memory and the actual elements yielded, causing use-after-free or memory corruption when creating raw slices.
