| 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 (affected versions not specified)
Description
The issue is related to the RDMA/hns module in the Linux kernel, where the refcount of CQ is not protected by locks. When CQ asynchronous events and CQ destruction are concurrent, CQ may have been released, which will cause a use-after-free (UAF) condition. This can be exploited to impact the confidentiality, integrity, and availability of protected information. The vulnerability is fixed by using the xa lock() to protect the CQ refcount.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
