This repository provides a proof-of-concept (PoC) local denial-of-service exploit for CVE-2024-20698, a vulnerability in the Windows kernel (ntoskrnl.exe) related to the WbAddLookupEntryEx function. The exploit consists of two main C++ programs: 'DoS_exploit' and 'NtQuerySysInfo_test'. 'DoS_exploit' attempts to create an extremely large number of concurrent processes, each running 'NtQuerySysInfo_test.exe'. The test executable calls the NtQuerySystemInformation API with a specific argument (0xB9), which triggers the vulnerable code path in the kernel. The exploit aims to cause an integer overflow during memory allocation in the kernel, leading to memory corruption and potential system instability or crash. The README provides a detailed technical analysis of the vulnerability, the patch, and the exploit strategy. The exploit is limited by the system's ability to create a massive number of processes, which may not be feasible on all systems, but demonstrates the vulnerability's impact. No network or remote attack vector is present; this is a local privilege exploit requiring code execution on the target system.
