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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 use-after-free issue in the Linux kernel's Bluetooth L2CAP component, specifically in the l2cap_le_command_rej function. It means that the system may attempt to use memory after it has been freed, which can lead to unexpected behavior or crashes.
How can this vulnerability impact me? :
The use-after-free vulnerability could potentially allow attackers to cause system instability, crashes, or possibly execute arbitrary code by exploiting the Bluetooth L2CAP component in the Linux kernel.
