The CVE-2024-38080 vulnerability is a race condition within the Windows Kernel. It stems from improper synchronization of a shared resource during concurrent execution. A locally authenticated attacker can exploit this flaw by creating a specific sequence of threads that manipulate a kernel object. One thread may trigger the object’s deletion while another, operating in parallel, continues to use the now-freed memory pointer. This creates a “use-after-free” scenario, corrupting kernel memory. By carefully controlling this corruption, the attacker can overwrite critical data structures to execute arbitrary code with elevated SYSTEM privileges, bypassing security boundaries.
Platform: Windows
Version: Multiple
Vulnerability : Race Condition
Severity: High
date: 2024-07-09
Prediction: 2024-08-13
What Undercode Say:
Simulating concurrent thread creation
for i in {1..5}; do (./exploit_thread &); done
// Pseudocode for thread operations HANDLE hObject = CreateKernelObject(); // Thread A CloseHandle(hObject); // Frees object // Thread B (concurrent) WriteToKernelMemory(hObject->pointer); // Use-after-free
How Exploit:
Local attacker executes code.
Spawns multiple competing threads.
Threads race on kernel object.
Causes use-after-free corruption.
Overwrites kernel memory.
Gains SYSTEM privileges.
Protection from this CVE
Apply Windows update.
Restrict user privileges.
Use exploit mitigation tools.
Impact:
Local Privilege Escalation.
Kernel Memory Corruption.
Full System Compromise.
