A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel prior to 5.3.9 allows malicious users to cause a denial of service (memory consumption) by triggering rhashtable_init() failures, aka CID-34b3be18a04e. 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).
