CVE-2021-46750
Estado: AplazadaBaja (3)—
Failure to validate the address and size in TEE (Trusted Execution Environment) may allow a malicious x86 attacker to send malformed messages to the graphics mailbox resulting in an overlap of a TMR (Trusted Memory Region) that was previously allocated by the ASP bootloader leading to a potential loss of integrity.
