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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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
How can this vulnerability impact me? :
If exploited, this vulnerability could allow an attacker who has compromised a child process in Firefox to escape the sandbox, potentially gaining higher privileges or access to sensitive parts of the system, leading to further exploitation or data compromise.
What immediate steps should I take to mitigate this vulnerability?
Update Firefox to version 144.0.2 or later to fix the use-after-free vulnerability related to WebGPU IPC calls and prevent potential sandbox escape.
Can you explain this vulnerability to me?
This vulnerability is a use-after-free issue in Firefox versions before 144.0.2, where a compromised child process can exploit WebGPU-related inter-process communication (IPC) calls to trigger memory corruption in the GPU or browser process. This could potentially allow the compromised process to escape its sandbox restrictions.
