Last modified

CVE-2021-46750 is a low-severity vulnerability rated 3/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
