Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.3.9

Description A memory leak in the sdma init() function in drivers/infiniband/hw/hfi1/sdma.c allows attackers to cause a denial of service (memory consumption) by triggering rhashtable init() failures. The issue is 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(), it is a pointer to a static const struct, so an attacker could only trigger failure if they could corrupt kernel memory.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
