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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 error in the Linux kernel related to the handling of ACPI tables loaded via EFI. Specifically, memory holding a new ACPI table was being freed unconditionally, even when the table was successfully loaded, which could lead to accessing freed memory. The fix involves not freeing the memory if the ACPI table was loaded successfully.
How can this vulnerability impact me? :
The use-after-free vulnerability could lead to system instability, crashes, or potentially allow an attacker to execute arbitrary code or cause denial of service by exploiting the improper memory handling in the ACPI table loading process.
