CVE-2021-36133
First published: Tue Dec 07 2021(Updated: )
The OPTEE-OS CSU driver for NXP i.MX SoC devices lacks security access configuration for several models, resulting in TrustZone bypass because the NonSecure World can perform arbitrary memory read/write operations on Secure World memory. This involves a DMA capable peripheral.
