How CVE-2025-24997 Works
This vulnerability occurs due to improper handling of null pointers in the Windows Kernel Memory Manager. When a malicious application sends a crafted system call with a null pointer reference, the kernel fails to validate the memory address before dereferencing it. This triggers a system crash (BSOD) due to an unhandled exception, leading to a local denial of service (DoS). Attackers with low privileges can exploit this flaw by repeatedly triggering the null pointer dereference, disrupting system availability.
