发布于3月6日3月6日 Members Huawei EulerOS: CVE-2021-3923: kernel security update Severity 1 CVSS (AV:L/AC:L/Au:M/C:P/I:N/A:N) Published 03/27/2023 Created 05/10/2023 Added 05/10/2023 Modified 01/30/2025 Description A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.
