In the Linux kernel, the following vulnerability has been resolved:
memory: renesas-rpc-if: fix possible NULL pointer dereference of resource
The platform_get_resource_byname() can return NULL which would be immediately dereferenced by resource_size(). Instead dereference it after validating the resource.
Addresses-Coverity: Dereference null return value
