Summary
CVE-2024-56689 is a newly identified vulnerability in the Linux kernel. This issue affects PCI endpoints with MHI (Media High Definition Interface) and could result in a NULL pointer dereference. Specifically, if the device tree lacks an 'mmio' property for the MHI endpoint, a call to platform_get_resource_byname() might return NULL, leading to a NULL pointer access if the subsequent res->start is dereferenced. The vulnerability has been resolved by adding a check to prevent this scenario.
