The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - gpiolib: fix race condition for gdev->srcu If two drivers were calling gpiochip_add_data_with_key(), one     may be traversing the srcu-protected list in gpio_name_to_desc(), meanwhile other has just added its gdev     in gpiodev_add_to_list_unlocked(). This creates a non-mutexed and non-protected timeframe, when one     instance is dereferencing and using &gdev->srcu, before the other has initialized it, resulting in crash:
