CVE-2021-34389
Trusty contains a vulnerability in NVIDIA OTE protocol message parsing code, which is present in all the TAs.
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
Trusty contains a vulnerability in NVIDIA OTE protocol message parsing code, which is present in all the TAs. An incorrect bounds check can allow a local user through a malicious client to access memory from the heap in the TrustZone, which may lead to information disclosure.
