Use After Free

memory HIGH

Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated.

How It Works

Use-after-free vulnerabilities occur when a program continues to access memory through a pointer after that memory has been deallocated. When memory is freed, it returns to the allocator's pool and may be reallocated for an entirely different purpose. The original pointer becomes "dangling"—it still points to that memory location, but the contents are now undefined or controlled by different code.

Attackers exploit this by orchestrating a three-step process: first, trigger the memory deallocation; second, cause the allocator to reassign that same memory region with attacker-controlled data (often through carefully timed allocations); third, trigger the program to dereference the dangling pointer. Because the memory now contains attacker data instead of the expected object, this can corrupt function pointers, vtables, or other critical structures.

The vulnerability is particularly dangerous in object-oriented code where freed objects contain function pointers or virtual method tables. When the program calls a method on the freed object, it may jump to attacker-controlled addresses. Browser engines are frequent targets because DOM manipulation allows attackers to control object allocation and deallocation timing through JavaScript, while kernel UAFs enable privilege escalation by manipulating file descriptors or process structures.

Impact

  • Arbitrary code execution — attacker overwrites function pointers or vtables to redirect program flow to malicious code
  • Privilege escalation — in kernel UAFs, gain root/system privileges by corrupting process credentials or security tokens
  • Information disclosure — read sensitive data from reallocated memory that wasn't properly cleared
  • Sandbox escape — break out of browser or application sandboxes by corrupting security-critical objects
  • Denial of service — crash the application through memory corruption, though attackers typically aim for exploitation rather than simple crashes

Real-World Examples

CVE-2021-30551 affected Chrome's V8 JavaScript engine, where improper handling of JavaScript typed arrays created a use-after-free in object property management. Attackers could trigger object deletion while retaining references, then reallocate the memory with controlled data to achieve code execution within the renderer process.

Windows kernel vulnerabilities like CVE-2020-17087 involved use-after-free conditions in the Windows keyboard layout handling code. Attackers exploited race conditions in keyboard layout switching to free kernel objects while retaining references, then reallocated the memory with controlled structures to elevate privileges from user to SYSTEM level.

The WhatsApp vulnerability CVE-2019-11932 demonstrated UAF exploitation in media parsing code, where specially crafted GIF files triggered premature memory deallocation. Subsequent access to the freed buffers allowed remote code execution without user interaction beyond receiving the malicious file.

Mitigation

  • Memory-safe languages — use Rust, Go, Swift, or other languages with automatic memory management
  • Smart pointers — employ RAII patterns and reference counting (unique_ptr, shared_ptr in C++)
  • AddressSanitizer (ASAN) — detect UAF during testing through instrumented builds
  • Immediate pointer nullification — set pointers to NULL after free() to cause immediate crashes rather than exploitable conditions
  • Garbage collection — languages with GC prevent manual memory management errors
  • Control Flow Integrity (CFI) — limits exploit impact by validating function pointer targets
  • Heap hardening — allocator metadata protection and delayed reuse policies increase exploitation difficulty
