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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 is a use-after-free issue in the Linux kernel's iommu/mediatek driver. It occurs because the driver drops references to larb devices during probe after successful lookup or errors. If a larb device has not yet been bound to its driver, the iommu driver probe defers, which can lead to use-after-free when those references are dropped prematurely. The fix involves keeping the references as expected while the iommu driver is bound.
How can this vulnerability impact me? :
This vulnerability can lead to use-after-free conditions in the kernel, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges if they can trigger the condition.
