Summary

thin-vec: Use-After-Free and Double Free in IntoIter::drop When Element Drop Panics

Details

Summary

A Double Free / Use-After-Free (UAF) vulnerability has been identified in the IntoIter::drop and ThinVec::clear implementations of the thin_vec crate. Both vulnerabilities share the same root cause and can trigger memory corruption using only safe Rust code — no unsafe blocks required. Undefined Behavior has been confirmed via Miri and AddressSanitizer (ASAN).

Details

Both vulnerabilities share the same root cause. When a panic occurs during sequential element deallocation, the subsequent length cleanup code (set_len(0)) is never executed. During stack unwinding, the container is dropped again, causing already-freed memory to be re-freed (Double Free / UAF).

Vulnerability 1 — `IntoIter::drop`

Location: thin-vec/src/lib.rs L.2308~2314

IntoIter::drop transfers ownership of the internal buffer via mem::replace, then sequentially frees elements via ptr::drop_in_place. If a panic occurs during element deallocation, set_len_non_singleton(0) is never reached. During unwinding, vec is dropped again, re-freeing already-freed elements. The standard library's std::vec::IntoIter prevents this with a DropGuard pattern, but thin-vec lacks this defense.

// Problematic structure (conceptual representation)
impl<T> Drop for IntoIter<T> {
    fn drop(&mut self) {
        let mut vec = mem::replace(&mut self.vec, ThinVec::new());
        unsafe {
            ptr::drop_in_place(vec.remaining_slice_mut()); // ← panic may occur here
            vec.set_len_non_singleton(0);                  // ← unreachable on panic
        }
        // During unwinding, vec is dropped again → Double Free
    }
}

Vulnerability 2 — `ThinVec::clear`

clear() calls ptr::drop_in_place(&mut self[..]) followed by self.set_len(0) to reset the length. If a panic occurs during element deallocation, set_len(0) is never executed. When the ThinVec itself is subsequently dropped, already-freed elements are freed again.

// Problematic structure (conceptual representation)
pub fn clear(&mut self) {
    unsafe {
        ptr::drop_in_place(&mut self[..]); // ← panic may occur here
        self.set_len(0);                   // ← unreachable on panic
    }
    // ThinVec drop later → Double Free
}

Recommended Fix

Both vulnerabilities can be resolved with the same pattern:

DropGuard pattern: Insert an RAII guard before drop_in_place to guarantee set_len(0) is called regardless of panic
Pre-zeroing approach: Set the length to 0 before calling drop_in_place

PoC

Requirements: Rust nightly toolchain, thin-vec = "0.2.14"

# Miri
cargo +nightly miri run

# ASAN
RUSTFLAGS="-Z sanitizer=address" cargo +nightly run --release

PoC-1: `IntoIter::drop`

use thin_vec::ThinVec;

struct PanicBomb(String);

impl Drop for PanicBomb {
    fn drop(&mut self) {
        if self.0 == "panic" {
            panic!("panic!");
        }
        println!("Dropping: {}", self.0);
    }
}

fn main() {
    let mut v = ThinVec::new();
    v.push(PanicBomb(String::from("normal1")));
    v.push(PanicBomb(String::from("panic")));  // trigger element
    v.push(PanicBomb(String::from("normal2")));

    let mut iter = v.into_iter();
    iter.next();
    // When iter is dropped: panic occurs at "panic" element
    // → During unwinding, Double Drop is triggered on "normal1" (already freed)
}

Miri output:

error: Undefined Behavior: pointer not dereferenceable:
       alloc227 has been freed, so this pointer is dangling

stack backtrace:
   3: <PanicBomb as Drop>::drop           ← Double Drop entry
   6: <ThinVec<T> as Drop>::drop::drop_non_singleton
   9: <IntoIter<T> as Drop>::drop::drop_non_singleton  ← lib.rs:2310 (root cause)

PoC-2: `ThinVec::clear`

use thin_vec::ThinVec;
use std::panic;

struct Poison(Box<usize>, &'static str);

impl Drop for Poison {
    fn drop(&mut self) {
        if self.1 == "panic" {
            panic!("panic!");
        }
        println!("Dropping: {}", self.0);
    }
}

fn main() {
    let mut v = ThinVec::new();
    v.push(Poison(Box::new(1), "normal1")); // index 0
    v.push(Poison(Box::new(2), "panic"));   // index 1 → panic triggered here
    v.push(Poison(Box::new(3), "normal2")); // index 2

    let _ = panic::catch_unwind(panic::AssertUnwindSafe(|| {
        v.clear();
        // panic occurs at "panic" element during clear()
        // → set_len(0) is never called
        // → already-freed elements are re-freed when v goes out of scope
    }));
}

Impact

Vulnerability classification: - CWE-415: Double Free - CWE-416: Use-After-Free

Affected code: All code satisfying the following conditions simultaneously:

ThinVec stores heap-owning types (String, Vec, Box, etc.)
(Vulnerability 1) An iterator is created via into_iter() and dropped before being fully consumed, or (Vulnerability 2) clear() is called while a remaining element's Drop implementation can panic
The Drop implementation of a remaining element triggers a panic

Additionally, when combined with Box<dyn Trait> types, an exploit primitive enabling Arbitrary Code Execution (ACE) via heap spray and vtable hijacking has been confirmed. If the freed fat pointer slot (16 bytes) at the point of Double Drop is reclaimed by an attacker-controlled fake vtable, subsequent Drop calls can be redirected to attacker-controlled code.

Severity

7.3 (High)

Vulnerability from github – Published: 2026-06-30 09:31 – Updated: 2026-08-25 12:31

Details

A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service.

Severity

7.5 (High)

GHSA-XV2M-P78G-CM3M

Vulnerability from github – Published: 2026-06-26 21:32 – Updated: 2026-07-08 06:31

Details

In the Linux kernel, the following vulnerability has been resolved:

idpf: fix double free and use-after-free in aux device error paths

When auxiliary_device_add() fails in idpf_plug_vport_aux_dev() or idpf_plug_core_aux_dev(), the err_aux_dev_add label calls auxiliary_device_uninit() and falls through to err_aux_dev_init. The uninit call will trigger put_device(), which invokes the release callback (idpf_vport_adev_release / idpf_core_adev_release) that frees iadev. The fall-through then reads adev->id from the freed iadev for ida_free() and double-frees iadev with kfree().

Free the IDA slot and clear the back-pointer before uninit, while adev is still valid, then return immediately.

Commit 65637c3a1811 ("idpf: fix UAF in RDMA core aux dev deinitialization") fixed the same use-after-free in the matching unplug path in this file but missed both probe error paths.

Severity

7.8 (High)

GHSA-XW98-8FCM-J8X7

Vulnerability from github – Published: 2026-08-07 18:31 – Updated: 2026-08-07 18:31

Details

A vulnerability in the zip archive parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition on an affected device.

This vulnerability is due to improper memory handling when processing content in zip files during scanning. An attacker could exploit this vulnerability by submitting a crafted zip file for scanning. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate as a result of a memory double-free, resulting in a DoS condition on the affected software.

Severity

7.5 (High)

GHSA-XWQ3-8G6Q-RQ5G

Vulnerability from github – Published: 2022-05-13 01:38 – Updated: 2022-05-13 01:38

Details

This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of Bitdefender Total Security 21.0.24.62. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within processing of the 0x8000E038 IOCTL in the bdfwfpf driver. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker could leverage this vulnerability to execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-4776.

Severity

7.0 (High)
