CVE-2024-26252

Physical-access code execution via untrusted pointer dereference

Published Apr 9, 2024 · Updated May 3, 2025

Untrusted pointer dereference in Microsoft Windows rndismp6.sys allows physically proximate attackers to execute code through a crafted USB device. The driver converts a value supplied by the connected device into a pointer and dereferences it without establishing that the address is trusted. Exploitation requires physical USB access and can execute code with kernel-level effects on confidentiality, integrity, and availability.
