Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/hns: Fix warning in poll cq direct mode

CQs allocated by iballoccq() always have a comphandler. Though in direct mode this handler is never expected to be called, it is still called when the driver is reset, triggering the following WARNONCE():
