How this entity was disambiguated
This entity first appeared as the object of triple T12280410 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: Memory Tagging Extension Context triple: [ARMv9-A, includesFeature, Memory Tagging Extension]
-
A.
TrustZone security extension
TrustZone security extension is ARM's hardware-based security technology that creates isolated execution environments to protect sensitive code and data on system-on-chip devices.
-
B.
Trusted Execution Environment
A Trusted Execution Environment (TEE) is a secure area of a main processor that runs isolated code and protects sensitive data from the rest of the system, even if the operating system is compromised.
-
C.
SMAP (Supervisor Mode Access Prevention)
SMAP (Supervisor Mode Access Prevention) is a CPU security feature that blocks kernel-mode code from unintentionally accessing user-space memory, helping to mitigate exploitation of memory corruption vulnerabilities.
-
D.
SMEP (Supervisor Mode Execution Prevention)
SMEP (Supervisor Mode Execution Prevention) is a CPU security feature that blocks the kernel from executing code located in user-space memory, helping prevent privilege escalation attacks.
-
E.
Enclave Page Cache
Enclave Page Cache is a protected memory region used by Intel SGX to store and manage the code and data of secure enclaves during execution.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
