CVE-2022-25258Public exploit

Device crash via unchecked USB interface index

Published Feb 16, 2022 · Updated Aug 3, 2024

Memory corruption in the Linux kernel before 5.16.10 allows physically proximate attackers to crash USB Gadget devices via control requests. The composite_setup function uses an unvalidated interface number from wValue to index a 16-entry interface array and can dereference a null function pointer. Exploitation requires exposed USB Gadget OS descriptors and physical control of the USB host; one crafted transfer can crash the device.
