In the Linux kernel, the following vulnerability has been resolved:
drm: bridge: cdns-mhdp8546: Fix possible null pointer dereference
In cdnsmhdpatomicenable(), the return value of drmmodeduplicate() is assigned to mhdpstate->currentmode, and there is a dereference of it in drmmodesetname(), which will lead to a NULL pointer dereference on failure of drmmodeduplicate().
