CVE-2021-46750: AMD Athlon 3000 Series Mobile Processors With Radeon Graphics

Low severity, CVSS 3.0. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
