Intel(R) Stratix 10 and Intel(R) Agilex 7 FPGAs: Unchecked Return Value
CVE-2023-41092 is a high-severity unchecked return value vulnerability in Intel(R) Stratix 10 and Intel(R) Agilex 7 FPGAs, with a CVSS 3.1 base score of 7.6 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. Affected Intel(R) Stratix 10 and Intel(R) Agilex 7 FPGAs versions: before version 23.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.33% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

The underlying weakness: Unchecked Return Value
The product does not check the return value from a method or function.
How developers prevent this class of flaw
- Check the results of all functions that return a value and verify that the value is expected.
- For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished.
- Ensure that you account for all possible return values from the function.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
