CVE-2026-24801: Medium Vulnerability in Ralim IronOS

CVE-2026-24801 is a medium-severity vulnerability in Ralim IronOS, specifically affecting the modules related to the Bluetooth stack and cryptographic routines. This vulnerability allows potential attackers to exploit the program files associated with ecc_dsa.C. The vulnerability has a CVSS score of 6.9, indicating a medium level of severity, which is critical for organizations to address to ensure the security of their systems.

The vulnerability affects all versions of IronOS prior to v2.23-rc3. Risk to organizations includes potential unauthorized access to sensitive data due to its high confidentiality and integrity impact ratings. Given the nature of the vulnerability, organizations should prioritize patching immediately to mitigate the associated risks.

As of now, there are no known exploits or public proof-of-concept (PoC) code for this vulnerability, and it is not currently listed in the Known Exploit Vulnerability (KEV) database. However, organizations should remain vigilant and monitor for any updates or potential exploitation as the situation evolves.

Organizations should take proactive measures not only to patch this vulnerability but also to enhance their overall security posture against similar issues in the future.

Vulnerability Details

CVE-2026-24801 is classified as a medium severity vulnerability with a CVSS score of 6.9. The vulnerability is associated with Ralim IronOS, particularly in the source/Core/BSP/Pinecilv2/bl_mcu_sdk/components/ble/ble_stack/common/tinycrypt/source modules. It is linked to the program files ecc_dsa.C, which are critical for cryptographic functions.

The vulnerability was published on January 27, 2026, and is classified under CWE-22, which indicates improper limitation of a pathname to a restricted directory (Path Traversal). The potential impact on confidentiality is high, as well as on integrity. However, the availability impact is noted as none.

Technical Analysis

The root cause of this vulnerability stems from improper access controls in the Bluetooth stack and cryptographic routines of Ralim IronOS. The attack vector for this vulnerability is physical, meaning that an attacker would need physical access to the device to exploit it. The attack complexity is considered low, as no special conditions need to be met for exploitation.

In terms of privileges required, none are necessary, and user interaction is also not required. This exacerbates the potential risk to the organization, as the vulnerability can be exploited without user consent or awareness.

The high-impact ratings on confidentiality and integrity suggest that successful exploitation could lead to unauthorized data access and modification. Organizations deploying Ralim IronOS should assess their security measures to protect against potential exploitation scenarios.

Risk & Impact Analysis

The real-world deployment risk associated with CVE-2026-24801 is moderate, given its physical attack vector and the implications for confidentiality and integrity. Organizations that rely on Ralim IronOS should recognize the potential for significant data breaches or unauthorized modifications if this vulnerability is exploited.

The blast radius potential is considerable, particularly in environments where sensitive data is processed or stored. As the exploitation status indicates no known active exploitation, the urgency for organizations to address this vulnerability should be integrated into their priority patch cycle.

Although the CVSS score is medium, organizations should not underestimate the impact of this vulnerability. Regular updates and proactive monitoring are essential to mitigate risks effectively.

Exploitation Status

Affected Versions

All versions of Ralim IronOS prior to v2.23-rc3 are affected by this vulnerability. Organizations utilizing these versions should evaluate the urgency of applying patches or updates.

Mitigation & Remediation

To mitigate CVE-2026-24801, organizations should implement the following steps:

1. Apply patches or updates to Ralim IronOS, specifically targeting versions after v2.23-rc3.

2. Implement configuration hardening to restrict access to critical modules, ensuring that only authorized personnel can interact with sensitive components.

3. Conduct continuous monitoring of systems to detect any unauthorized access attempts or anomalies.

Organizations should also consider engaging in penetration testing to identify any additional vulnerabilities in their deployments.

Detection Guidance

Organizations should monitor logs for indicators of unauthorized access attempts, specifically focusing on any interactions with the ecc_dsa.C program files. Behavioral anomalies, such as unexpected changes in access patterns or configurations, should also be flagged for further investigation.
