For Linux kernel versions through 5.16-rc6, as a temporary workaround, consider disabling the
uapi finalize() function until a patch is available. Restrict access to the drivers/infiniband/core/uverbs uapi.c module to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.NULL Pointer Dereference
