CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:N
Summary
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.
