- [none]
- Details
-
A memory leak in the sdmainit() 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 rhashtableinit() failures, aka CID-34b3be18a04e. NOTE: This has been disputed as not a vulnerability because "rhashtableinit() can only fail if it is passed invalid values in the second parameter's struct, but when invoked from sdmainit() 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).
