  "details": "In the Linux kernel, the following vulnerability has been resolved:  hwmon: (powerz) Fix use-after-free on USB disconnect  After powerz_disconnect() frees the URB and releases the mutex, a subsequent powerz_read() call can acquire the mutex and call powerz_read_data(), which dereferences the freed URB pointer.  Fix by:  - Setting priv-\u003eurb to NULL in powerz_disconnect() so that    powerz_read_data() can detect the disconnected state.  - Adding a !priv-\u003eurb check at the start of powerz_read_data()    to return -ENODEV on a disconnected device.  - Moving usb_set_intfdata() before hwmon registration so the    disconnect handler can always find the priv pointer.",
