CVE-2025-0038 is a vulnerability identified in AMD's Zynq UltraScale+ devices, particularly impacting the Kria System on Module (SOM) platform. The root cause is an improper validation of specified quantities in input, classified under CWE-1284, which relates to insufficient validation of parameters controlling memory access. Specifically, the vulnerability exists in the PMU (Power Management Unit) Firmware's handling of CSU (Central Security Unit) runtime services. When these services are invoked, the firmware fails to adequately validate the addresses provided, which can allow an attacker with local privileges to access memory regions that are intended to be isolated or protected. This unauthorized memory access can lead to a breach of confidentiality by exposing sensitive data and compromise integrity by allowing modification of protected memory contents. The attack vector is local (AV:L), requiring low privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The CVSS v3.1 base score is 6.6, reflecting a medium severity level with partial impact on confidentiality and integrity and a high impact on availability. No public exploits are known at this time, and no patches have been released yet, though the vendor has reserved the CVE and is presumably working on remediation. The vulnerability is particularly relevant for embedded systems and industrial applications where AMD Kria SOM devices are deployed, as these environments often rely on the integrity and confidentiality of firmware and memory protections to maintain operational security.

For European organizations, especially those in industrial automation, telecommunications, and critical infrastructure sectors that utilize AMD Kria SOM or similar Zynq UltraScale+ devices, this vulnerability could lead to unauthorized disclosure or modification of sensitive data stored in protected memory areas. This could result in operational disruptions, intellectual property theft, or compromise of safety-critical systems. The local attack requirement limits remote exploitation but insider threats or compromised local devices could leverage this flaw. Loss of integrity and confidentiality in embedded systems can cascade into broader system failures or data breaches. Given the increasing adoption of embedded AI and edge computing platforms in Europe, the vulnerability poses a tangible risk to sectors such as manufacturing, automotive, and energy. The absence of known exploits reduces immediate risk but also underscores the importance of proactive mitigation before public exploitation occurs.

Organizations should monitor AMD’s advisories closely and apply firmware updates or patches as soon as they become available. Until patches are released, restrict local access to devices running the vulnerable PMU firmware to trusted personnel only, employing strict physical and logical access controls. Implement runtime service access restrictions and audit logs to detect unauthorized attempts to invoke CSU runtime services. Employ hardware security modules or trusted execution environments where possible to isolate critical firmware operations. Conduct thorough security assessments of embedded systems incorporating AMD Kria SOM to identify potential attack vectors. Additionally, consider network segmentation to limit lateral movement from compromised local devices. Finally, maintain an incident response plan tailored to embedded device compromises to quickly contain and remediate any exploitation attempts.
