CVE-2019-19065

DISPUTED A memory leak in the sdma_init() function in
drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before 5.3.9 allows
attackers 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).”
