CVE-2024-56689
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
PCI: endpoint: epf-mhi: Avoid NULL dereference if DT lacks 'mmio'
If platform_get_resource_byname() fails and returns NULL because DT lacks an 'mmio' property for the MHI endpoint, dereferencing res->start will cause a NULL pointer access. Add a check to prevent it.
