CVE-2024-36345 is a medium-severity Improper Access Control for Volatile Memory Containing Boot Code (CWE-1274) vulnerability in Amd (inferred from references). Its CVSS base score is 4.6 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Pre-OS Boot (T1542); ranked at the 1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Vulnerability Data
Improper input validation in the AMD OverDrive (AOD) System Management Mode (SMM) module could allow a privileged attacker to perform an out-of-bounds read, potentially resulting in loss of confidentiality.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly enforces access authorizations on system resources including the volatile memory region holding boot code.
AC-6 restricts privileges so that only authorized processes can access the volatile memory containing boot code.
SC-3 isolates security functions such as boot code from non-security code, structurally preventing unauthorized access to the VM region.
SC-39 maintains separate execution domains that can isolate bootloader code loaded into volatile memory.

PR.DS-10 directly requires protecting data-in-use (including VM) from unauthorized access, eliminating most of this specific boot-code exposure, yet the weakness also spans secure-boot process design and NVM-to-VM transfer that one general data-protection outcome does not fully close.

Logging can detect unauthorized writes to volatile memory but does not prevent the weakness.
Restricting privileged utilities reduces the chance of tampering with boot code in volatile memory.
Privileged access rights can limit who or what can write to volatile memory used for boot code.
Secure system architecture principles include memory protection mechanisms that can mitigate this weakness.
Information access restriction directly addresses unauthorized access to volatile memory holding boot code.
