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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 in the Linux kernel's cpufreq davinci driver involves a use-after-free issue. Specifically, the remove function frees clock resources before unregistering the cpufreq driver. If a cpufreq callback is triggered just before the driver is unregistered, it may attempt to use the already freed clock resources, leading to potential instability or crashes.
How can this vulnerability impact me? :
The vulnerability can cause system instability or crashes due to the use of freed clock resources in the cpufreq driver. This may affect system performance or reliability, especially on systems using the affected driver.
