CVE-2023-48698

Physical code execution via expired pointer dereference

Published Dec 5, 2023 · Updated Nov 27, 2024

Expired-pointer dereferences in Eclipse ThreadX USBX before 6.3.0 allow physically proximate attackers to execute arbitrary code. The host hub-entry and EHCI isochronous-endpoint creation paths dereference objects after their backing memory has been freed; linked host-class code includes GSER and HID. Exploitation requires a crafted USB device to reach an affected embedded USB host, with unauthorized code execution and resulting confidentiality and integrity loss.
