Detailsinfo

A vulnerability classified as problematic was found in NVIDIA ConnectX-5, ConnectX-6 and ConnectX6-DX (version unknown). This vulnerability affects an unknown function of the component NIC Firmware. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. The CWE definition for the vulnerability is CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. As an impact it is known to affect availability. CVE summarizes:

NVIDIA ConnectX-5, ConnectX-6, and ConnectX6-DX contain a vulnerability in the NIC firmware, where an unprivileged user can exploit insufficient granularity of access control, which may lead to denial of service.

The weakness was released 04/22/2023. The advisory is available at nvidia.custhelp.com. This vulnerability was named CVE-2023-0205 since 01/11/2023. The technical details are unknown and an exploit is not available.
