The aiptek_probe function in drivers/input/tablet/aiptek.c in the Linux kernel before 4.4 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device that lacks endpoints.
An out-of-bounds memory access flaw was found in the Linux kernel's aiptek USB tablet driver (aiptek_probe() function in drivers/input/tablet/aiptek.c). The driver assumed that the interface always had at least one endpoint. By using a specially crafted USB device with no endpoints on one of its interfaces, an unprivileged user with physical access to the system could trigger a kernel NULL pointer dereference, causing the system to panic.
Отчет
This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, 7 and MRG-2, as the driver with the flaw is present in the products listed. This has been rated as having Low security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.
