Common Weakness Enumeration
CWE-122
AllowedHeap-based Buffer Overflow
Abstraction: Variant · Status: Draft
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
4096 vulnerabilities reference this CWE, most recent first.

Summary
smallbitvec: Integer overflow in safe API leads to heap buffer overflow
Details
Summary
An integer overflow in the internal capacity calculation of smallbitvec can lead to an undersized heap allocation, resulting in a heap buffer overflow through safe APIs only. This allows memory corruption without requiring unsafe code from the caller.
Details
The issue originates from unchecked arithmetic in the internal helper function responsible for computing the required buffer size:
(cap + bits_per_storage() - 1) / bits_per_storage()
When cap is close to usize::MAX, the addition:
cap + bits_per_storage() - 1
can overflow in release builds and wrap around due to Rust’s default wrapping semantics for integer overflow in optimized builds.
As a result:
- buffer_len(cap) may return a value significantly smaller than required.
- The backing storage is allocated with insufficient size.
- Internal metadata (logical length/capacity) reflects a much larger size than the actual allocation.
Subsequent safe API calls (e.g., set, push, reserve) rely on this corrupted metadata and perform index computations that assume sufficient backing storage. These operations eventually reach unsafe internal code paths (e.g., pointer arithmetic and unchecked indexing), leading to out-of-bounds memory access.
Summary of the issue: integer overflow → undersized allocation → inconsistent metadata (len/cap vs actual buffer) → unsafe internal access using corrupted metadata → heap buffer overflow (UB)
PoC
PoC 1: Out-of-bounds write via from_elem
#![forbid(unsafe_code)]
use smallbitvec::SmallBitVec;
fn main() {
// Triggers overflow in buffer_len(cap)
let mut v = SmallBitVec::from_elem(usize::MAX, false);
// Logical length is large, but backing storage is undersized
// This leads to out-of-bounds write in unsafe internals
v.set(0, true);
}
PoC 2: Overflow via reserve
#![forbid(unsafe_code)]
use smallbitvec::SmallBitVec;
fn main() {
let mut v = SmallBitVec::new();
v.push(true);
// Triggers overflow in capacity computation
v.reserve(usize::MAX - 10);
}
Impact
- Heap buffer overflow via safe API only
- ASAN-observable heap-buffer-overflow
- Undefined Behavior detectable with Miri (e.g., out-of-bounds indexing due to corrupted metadata)
Tested on
- rustc 1.96.0-nightly (9602bda1d 2026-04-05)
- Target: x86_64-unknown-linux-gnu
- Build: release
- ASAN:
RUSTFLAGS="-Z sanitizer=address" cargo +nightly run --release - Miri:

Mitigation
Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation MIT-10
Operation
Build and Compilation
Strategy: Environment Hardening
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
- D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation MIT-11
Operation
Build and Compilation
Strategy: Environment Hardening
- Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
- Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
- For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
Mitigation
Implementation
Implement and perform bounds checking on input.
Mitigation
Implementation
Strategy: Libraries or Frameworks
Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation
Operation
Use OS-level preventative functionality. This is not a complete solution, but it provides some defense in depth.
CAPEC-92: Forced Integer Overflow
This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
