CVE-2021-36133 unimportant priority: Debian including 1 source packages (optee-os), 3 status rows across 3 suites (forky, sid, trixie): open 3.
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.
