Title
HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()
Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()
The system can experience a random crash a few minutes after the driver is
removed. This issue occurs due to improper handling of memory freeing in
the ishtp_hid_remove() function.
The function currently frees the `driver_data` directly within the loop
that destroys the HID devices, which can lead to accessing freed memory.
Specifically, `hid_destroy_device()` uses `driver_data` when it calls
`hid_ishtp_set_feature()` to power off the sensor, so freeing
`driver_data` beforehand can result in accessing invalid memory.
This patch resolves the issue by storing the `driver_data` in a temporary
variable before calling `hid_destroy_device()`, and then freeing the
`driver_data` after the device is destroyed.

This issue occurs due to improper handling of memory freeing in\nthe ishtp_hid_remove() function.\n\nThe function currently frees the `driver_data` directly within the loop\nthat destroys the HID devices, which can lead to accessing freed memory.\nSpecifically, `hid_destroy_device()` uses `driver_data` when it calls\n`hid_ishtp_set_feature()` to power off the sensor, so freeing\n`driver_data` beforehand can result in accessing invalid memory.\n\nThis patch resolves the issue by storing the `driver_data` in a temporary\nvariable before calling `hid_destroy_device()`, and then freeing the\n`driver_data` after the device is destroyed."

Este problema se produce debido a la gesti\u00f3n incorrecta de la liberaci\u00f3n de memoria en la funci\u00f3n ishtp_hid_remove(). La funci\u00f3n actualmente libera `driver_data` directamente dentro del bucle que destruye los dispositivos HID, lo que puede llevar al acceso a la memoria liberada. Espec\u00edficamente, `hid_destroy_device()` usa `driver_data` cuando llama a `hid_ishtp_set_feature()` para apagar el sensor, por lo que liberar `driver_data` de antemano puede resultar en el acceso a memoria no v\u00e1lida. Este parche resuelve el problema almacenando `driver_data` en una variable temporal antes de llamar a `hid_destroy_device()` y luego liberando `driver_data` despu\u00e9s de que se destruye el dispositivo."
