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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 involves a use-after-free issue related to the handling of the input device name in the nvidia-shield HID driver. Specifically, the input device name was allocated without properly using the hid_device devm allocation, leading to the name being freed prematurely during device unregistration. This caused the system to use a freed name in a uevent, which can lead to undefined behavior or potential security issues.
How can this vulnerability impact me? :
The use-after-free vulnerability could lead to system instability or potential security risks such as crashes or exploitation by attackers to execute arbitrary code or cause denial of service on affected devices using the nvidia-shield HID driver.
