Summary

CVE-2025-29948 is a medium-severity Improper Handling of Overlap Between Protected Memory Ranges (CWE-1260) vulnerability in Amd (inferred from references). Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Process Injection (T1055); ranked at the 4th 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 SC-39 (Process Isolation) and SI-16 (Memory Protection) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-39 Process Isolation good match

Process isolation depends on correct non-overlapping memory protection domains.

SI-16 Memory Protection good match

Memory protection mechanisms must correctly handle ranges to block unauthorized execution or access.

AC-3 Access Enforcement partial match

Access enforcement directly stops bypass of memory protections that overlapping ranges would enable.

SC-3 Security Function Isolation partial match

Isolating security functions requires non-overlapping protected memory ranges to avoid bypass.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure development practices directly prevent flawed memory-range overlap logic in kernels and hypervisors.

ID.RA-01 partial match
prevents

Vulnerability identification can surface overlap defects after they are introduced but does not stop them at design time.

PR.AA-05 partial match
prevents

Enforcing access-control policy can include memory-range permissions, yet the weakness is an implementation flaw inside that enforcement.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance can detect overlap issues but does not itself prevent them.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles require explicit memory-range separation and protection mechanisms that directly prevent overlapping protected regions.

A.8.28 Secure coding partial match
prevents

Secure coding standards mandate checks for address-range overlap and proper memory-protection configuration, mitigating the weakness at implementation time.

A.8.3 Information access restriction partial match
mitigates

Information access restriction policies rely on correct memory protection; eliminating overlap strengthens enforcement but does not define the policy.
