Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-11326 is a critical stack-based buffer overflow vulnerability in the Tenda AC18 router firmware version 15.03.05.19(6318). It occurs in the /goform/WifiMacFilterSet functionality when the wifi_chkHz argument is manipulated improperly. This causes a stack overflow, where data overwrites memory on the stack, potentially allowing an attacker to compromise the device's confidentiality, integrity, and availability. The vulnerability can be exploited remotely without physical access, and a proof-of-concept exploit is publicly available. [1, 2]
How can this vulnerability impact me? :
This vulnerability can allow a remote attacker to execute arbitrary code or cause a denial of service on the affected Tenda AC18 router. Exploiting the stack-based buffer overflow could compromise the device's confidentiality, integrity, and availability, potentially leading to unauthorized control over the router or disruption of network services. [1, 2]
What immediate steps should I take to mitigate this vulnerability?
No known mitigations or countermeasures have been identified for this vulnerability. It is recommended to consider replacing the affected product, the Tenda AC18 router with firmware version 15.03.05.19(6318), to mitigate the risk. [1]
