Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is an Integer Overflow or Wraparound issue in the IronOS operating system, specifically in the function xQueueGenericCreate(). It occurs because the function did not have a critical security patch that was applied to the original FreeRTOS implementation. The overflow can happen during queue creation when adding values, potentially leading to unexpected behavior or security risks. The issue was fixed by adding an assertion to prevent addition overflow during queue creation. [1]
How can this vulnerability impact me? :
The vulnerability can lead to severe impacts including complete compromise of confidentiality, integrity, and availability of the affected system, as indicated by the high CVSS score (9.8) with high impact on confidentiality, integrity, and availability. An attacker could exploit the integer overflow to cause unexpected behavior, potentially allowing remote code execution or denial of service without any privileges or user interaction. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability relates to an integer overflow in the xQueueGenericCreate() function in IronOS. Detection would involve auditing the IronOS version running on your system to check if it is before v2.23-rc2, as those versions are affected. There are no specific network detection commands provided. To detect the vulnerable code, you can check the IronOS source code or firmware version. No direct commands for detection on a running system or network are provided in the resources. [1]
What immediate steps should I take to mitigate this vulnerability?
The immediate mitigation step is to update IronOS to version v2.23-rc2 or later, where the vulnerability has been fixed by applying a patch that adds an assertion to prevent addition overflow during queue creation. Applying this update will eliminate the security risk associated with CVE-2026-24830. [1]
