CVE-2021-3923

2.3 lowEPSS 0.2%

Low (2.3). EPSS 0.2% chance of exploitation in the next 30 days.

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.
