Exploitability
| CWE ID | Description |
|---|---|
| CWE-416 | The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a use-after-free issue in the Linux kernel's wifi component, specifically in the cfg80211 subsystem related to wireless extensions (wext). The problem occurs because key information in wext.connect is not reset during (re)connect, causing it to retain data from a previous connection. This can lead to drivers or the mac80211 subsystem incorrectly detecting a WEP connection request and accessing memory that has already been freed or reused, potentially causing instability or security issues.
How can this vulnerability impact me? :
The vulnerability can cause the system to access freed or reused memory incorrectly, which may lead to crashes, instability, or unintended behavior in the wireless networking stack. This could potentially be exploited to cause denial of service or other security issues related to wireless connections.
