Exploitability
CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-1220 | The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is due to improper input validation in the system management mode (SMM), which could allow a privileged attacker to overwrite arbitrary memory. This memory overwrite could potentially lead to arbitrary code execution at the SMM level.
How can this vulnerability impact me? :
An attacker with high privileges could exploit this vulnerability to execute arbitrary code at the system management mode level, potentially compromising system integrity, confidentiality, and availability.
