kernel: regulator: rt4801: Fix NULL pointer dereference if priv->enable_gpios is NULL
In the Linux kernel, the following vulnerability has been resolved:
regulator: rt4801: Fix NULL pointer dereference if priv->enable_gpios is NULL
devm_gpiod_get_array_optional may return NULL if no GPIO was assigned.
A vulnerability was found in the Linux kernel's regulator driver for the RT4801. The issue occurs when the function tries to access a GPIO setting, but it fails because the associated pointer is NULL which lead to crash the system when the system attempts to use these GPIOs without proper checks.
Statement: None of the products shipped by Red Hat are affected by this vulnerability.
Mitigation: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been a
