CVE-2024-1096Public exploit

System crash via fildds.sys IOCTL null dereference

Published Feb 13, 2024 · Updated Aug 27, 2024

NULL pointer dereference in Twister Antivirus 8.17 allows local users to crash Windows through crafted fildds.sys IOCTL requests. The fildds.sys IOCTL handler reads from a null-based address while processing any of sixteen disclosed control codes, causing a blue-screen system crash. Low-privilege local access is required, and successful exploitation interrupts the entire Windows host rather than only the antivirus process.
