Subject: Re: [PATCH for-next] RDMA/uverbs: Zero the QP attrs in ib_uverbs_query_qp

In-Reply-To: <20261104200244.52979-1-selvin.xavier@broadcom.com>
> ib_uverbs_query_qp() allocates qp_attr and qp_init_attr without zeroing
> and copies fields such as alt_ah_attr, path_mig_state and sq_draining
> to userspace. Drivers are not required to set every field in their
> query_qp() callback, so uninitialized kernel heap memory can leak.

> Allocate both structures zeroed.
