CVE‑2021‑34393	Trusty contains a vulnerability in TSEC TA which deserializes the incoming messages even though the TSEC TA does not expose any command. This vulnerability might allow an attacker to exploit the deserializer to impact code execution, causing information disclosure.	4.2	AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:N/A:N
CVE‑2021‑34394	Trusty contains a vulnerability in the NVIDIA OTE protocol that is present in all TAs.
