CVE-2022-48866

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: HID: hid-thrustmaster: corrige la lectura OOB en Thrustmaster_interrupts Syzbot informó un error de lectura fuera de los límites en Thrustmaster_probe(). El caso raíz es la falta de verificación de validación del número real de endpoints. El código no debe acceder ciegamente a usb_host_interface::endpoint array, ya que puede contener menos endpoints de los que espera el código. Solucionelo agregando una verificación de validación faltante e imprima un error si el número de endpoints no coincide con el número esperado

A vulnerability was found in the thrustmaster_interrupts function in the Linux kernel's HID Thrustmaster driver. This issue arises from a lack of validation for the actual number of endpoints, leading to a slab-out-of-bounds read when the code accesses the endpoint array.

In the Linux kernel, the following vulnerability has been resolved: HID: hid-thrustmaster: fix OOB read in thrustmaster_interrupts Syzbot reported an slab-out-of-bounds Read in thrustmaster_probe() bug. The root case is in missing validation check of actual number of endpoints. Code should not blindly access usb_host_interface::endpoint array, since it may contain less endpoints than code expects. Fix it by adding missing validaion check and print an error if number of endpoints do not match expected number
