| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.58
Description
A Use-After-Free vulnerability has been identified in the Linux kernel, specifically in the RDMA/hns component on HIP08. The issue arises when
rsv qp is freed before ib unregister device() is called, allowing users to still deregister MR and use rsv qp in this process, leading to a Use-After-Free. This vulnerability may allow an attacker to impact the confidentiality, integrity, and availability of protected information.Recommendations
For Linux kernel versions prior to 6.6.58, update to version 6.6.58 or later to resolve the issue. As a temporary workaround, consider restricting access to the
RDMA/hns component on HIP08 until a patch is available. Avoid using the rsv qp variable in the affected process until the issue is resolved.Exploit
