Descriptions

In the Linux kernel, the following vulnerability has been resolved:

net: hns3: fix kernel crash when devlink reload during pf initialization

The devlink reload process will access the hardware resources,
but the register operation is done before the hardware is initialized.
So, processing the devlink reload during initialization may lead to kernel
crash. This patch fixes this by taking devl_lock during initialization.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: hns3: soluciona el fallo del kernel cuando devlink se recarga durante la inicialización de pf. El proceso de recarga de devlink accederá a los recursos de hardware, pero la operación de registro se realiza antes de que se inicialice el hardware. Por lo tanto, procesar la recarga de devlink durante la inicialización puede provocar una falla del kernel. Este parche soluciona este problema tomando devl_lock durante la inicialización.
