NOTE: This has been disputed as not a vulnerability because \rhashtable_init() can only fail if it is passed invalid values in the second parameter’s struct but when invoked from sdma_init() that is a pointer to a static const struct so an attacker could only trigger failure if they could corrupt kernel memory (in which case a small memory leak is not a significant problem).\
