In the Linux kernel, the following vulnerability has been resolved: crypto: rk3288 - Fix use after free in unprepare The unprepare call must be carried out before the finalize call as the latter can free the request.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
