Use after free in DAL subsystem for Intel(R) CSME versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70, 13.0.40, 13.30.10, 14.0.45 and 14.5.25, Intel(R) TXE 3.1.80, 4.0.30 may allow an authenticated user to potentially enable escalation of privileges via local access.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
