Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix Use-After-Free of rsv_qp on HIP08 Currently rsv_qp is freed before ib_unregister_device() is called on HIP08. During the time interval, users can still dereg MR and rsv_qp will be used in this process, leading to a UAF. Move the release of rsv_qp after calling ib_unregister_device() to fix it.
