Exploitability
CWE
KEV
| 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 memory corruption issue that occurs when a user space address is modified and then passed to the mem_free API. This causes kernel memory to be freed unintentionally, which can lead to instability or exploitation of the system.
How can this vulnerability impact me? :
The vulnerability can have a high impact by allowing unauthorized modification or corruption of kernel memory. This can lead to system crashes, data corruption, or potentially allow an attacker to execute arbitrary code with elevated privileges.
