  "details": "In the Linux kernel, the following vulnerability has been resolved:  gpio: shared: gracefully handle no-device lookup of shared GPIOs  We use platform lookup tables for shared GPIOs. This mechanism needs a struct device to work so fwnode-based lookup with no device associated currently causes a NULL-pointer deference.  Adding this functionality will require a larger rework and it has never worked anyway so add a check that allows the kernel to gracefully handle this situation with an error ahead of implementing that functionality as a new feature.",
