CVE-2026-37540
8.4OpenAMP · OpenAMP
OpenAMP ELF loader contains an integer overflow vulnerability during firmware image parsing, leading to potential high severity impacts on embedded systems.
Executive summary
An integer overflow vulnerability in the OpenAMP ELF loader affects v2025.10.0 and allows attackers to cause wrap around conditions on 32-bit embedded systems, risking total system compromise.
Vulnerability
This is an integer overflow vulnerability within the elf_loader.c component, specifically through the multiplication of attacker-controlled values from the ELF header without bounds checking, requiring local access with no prior privileges.
Business impact
A successful exploit against this vulnerability can lead to severe consequences on embedded devices, including complete system failure, data corruption, or unauthorized code execution. With a CVSS score of 8.4, the risk is classified as high due to the potential for total technical impact on critical infrastructure and embedded hardware running affected software stacks.
Remediation
Immediate Action: Apply security updates provided by the OpenAMP maintainers or disable untrusted firmware loading until a validated patch is deployed.
Proactive Monitoring: Monitor embedded device boot logs and system telemetry for unexpected reboots, memory faults, or anomalous firmware parsing errors.
Compensating Controls: Restrict physical and local access to the target embedded devices and implement strict verification of signed firmware binaries before loading.
Exploitation status
Public Exploit Available: Yes, a public proof-of-concept exists via a referenced GitHub Gist.
Analyst recommendation
Security teams must treat this vulnerability with high urgency given the potential for total technical impact on embedded systems. Administrators should coordinate with hardware vendors to secure firmware update channels and apply available patches as soon as they are released.
