Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability occurs because the Trusted Execution Environment (TEE) fails to properly validate the address and size parameters. A malicious x86 attacker can exploit this by sending malformed messages to the graphics mailbox, causing an overlap of a Trusted Memory Region (TMR) that was previously allocated by the ASP bootloader. This overlap can lead to a potential loss of integrity in the system.
How can this vulnerability impact me? :
The impact of this vulnerability is a potential loss of integrity within the Trusted Execution Environment. An attacker exploiting this flaw could cause memory regions to overlap improperly, which might allow unauthorized modification or corruption of sensitive data or code within the TEE.
